[Human Capital Survey: Electronic Parts & Devices] Comparison of Male Paternity Leave x Female Managers x Paid Leave at 5 Major Companies Based on Primary Information | Keyence and Murata Manufacturing Exceed 70% Male Paternity Leave

Career Reveal, an open human capital data infrastructure operated by F. Peri Inc., has cross-compared and visualized KPIs related to human capital (diversity, male paternity leave, paid leave) in a ranked format based on primary information such as securities reports, integrated reports, and sustainability reports for five major companies in the electronic parts and devices industry (Keyence, TDK, Murata Manufacturing, Nidec, and Kyocera).

In the electronic parts and devices industry, which supports smartphones, EVs, and IoT devices, investment in people and promotion of diversity are becoming sources of long-term competitiveness. This release cross-compares three indicators – male paternity leave adoption rate, female manager ratio, and paid leave adoption rate – and organizes the differences in each company's HR policies and corporate culture behind the numbers.

※The data for each company published in this release generally refers to the latest disclosure (FY2025), but for indicators where FY2025 disclosure is unavailable, the most recent disclosure (FY2024) is referenced. Please note that Nidec's male paternity leave adoption rate (47.4%) is based on FY2024 disclosure.

■ Survey Results Summary

• Regarding male paternity leave adoption rates, Keyence at 72.9% and Murata Manufacturing at 72.0% exceeded 70%, ranking first and second. The average for the five companies, 56.2%, is on par with the average for four semiconductor manufacturing equipment companies (57.5%), suggesting that the system is becoming established throughout the industry.

• Kyocera is at 34.2%, the lowest among the five companies. However, it explicitly states "Promotion of Male Childcare Leave Acquisition" as an HR measure, indicating room for future improvement.

• The ratio of female managers is in the 4-8% range for all companies (average of 5.8% for the four that disclosed). Including Nidec at the top with 8.1%, this is thought to reflect the industry's inherent structural challenge of a shortage of STEM talent. Keyence's data is not disclosed.

• The average paid leave adoption rate for the four companies that disclosed is 75.6%, a high level significantly exceeding the average for all industries (around 60%). Kyocera leads with approximately 80%, followed by Nidec and TDK at about 73%. Keyence's data is not disclosed.

• Comprehensively considering the three indicators, Murata Manufacturing, with male paternity leave at 72.0%, paid leave at 76%, and female managers at 4.0%, shows a "balanced type across all diversity items." Nidec, with female managers at 8.1% (highest among the five) and male paternity leave at 47.4% (FY2024), exhibits a trend of being a "leader in female advancement."

■ Male Paternity Leave Adoption Rate Ranking

▼Career Reveal Editorial Department Analysis (Male Paternity Leave)▼

Keyence and Murata Manufacturing stand out, both exceeding 70%. Keyence is known for its "separation of public and private life model," but actively promotes the acquisition of male paternity leave, suggesting that its "work within core hours" productivity culture is compatible with leave acquisition. Murata Manufacturing also places "creating a workplace where everyone can work and thrive easily" at the core of its HR policy, and the generalization of childcare leave is reflected in the numbers. On the other hand, Kyocera is at 34.2%, the lowest among the five companies, but has clearly stated improvement measures, indicating it is in a transitional period.

■ Female Manager Ratio Ranking

▼Career Reveal Editorial Department Analysis (Female Managers)▼

The average of 5.8% for the four disclosed companies exceeds the average for four semiconductor manufacturing equipment companies (4.9%), but remains low compared to the average for all industries (around 15%). This is primarily attributed to the structurally low proportion of women in the pool of science and engineering talent, a challenge common not only to the electronic parts and devices industry but to manufacturing in general. Nidec's top figure of 8.1% is seen as a reflection of its commitment to its management policy of "Global Diversity, Equity & Inclusion." Keyence's non-disclosure of its female manager ratio also highlights differences in corporate policies regarding disclosure.

■ Paid Leave Adoption Rate Ranking

▼Career Reveal Editorial Department Analysis (Paid Leave)▼

The average of 75.6% for the four disclosed companies significantly exceeds the average for all industries (around 60%), indicating from primary information that the "electronic parts and devices industry is an industry where paid leave is easy to take." Kyocera, in particular, leads with 80%, reflecting the results of workplace reforms such as flexible work systems and the adoption of free address office layouts. TDK and Nidec also maintain high levels, around 73% to 74%. Keyence also does not disclose its paid leave adoption rate; while it has a policy of "prohibiting work brought home on weekdays and work-related contact on holidays" to separate public and private life, it cannot be referenced as quantitative verification material.

■ Career Reveal's Comprehensive Analysis

According to Career Reveal's analysis, the human capital KPIs of the five major electronic parts and devices companies are classified into the following "types."

・Keyence: [Ultra-high salary, separation of public and private life type] Maintains a high level of male paternity leave at 72.9%, while female manager and paid leave data are undisclosed. Its culture of "separation of public and private life" and "completion within core hours" is prominent.

・TDK: [Global balanced type] At moderate levels across all indicators: male paternity leave 54.5%, female managers 5.3%, and paid leave approximately 73%. It offers flexible systems such as super-flex and remote work.

・Murata Manufacturing: [Diversity balanced type] Shows well-balanced high levels across all three indicators: male paternity leave 72.0%, paid leave 76%, and female managers 4.0%. Its policy of "creating a workplace where everyone can thrive" appears to be reflected in the numbers.

・Nidec: [Leader in female advancement type] Leads in female advancement indicators with 8.1% female managers (highest among the five) and approximately 73% paid leave. Male paternity leave at 47.4% (FY2024) is still in the process of improvement, and balancing overall DEI will be a focus going forward.

・Kyocera: [Highest paid leave, paternity leave challenge type] Contrasts its highest paid leave rate at approximately 80% (highest among the five) with the lowest male paternity leave at 34.2% (lowest among the five). Balancing flexible work systems and paternity leave promotion is seen as the next challenge.

Overall, while the five major electronic parts and devices companies boast high paid leave adoption rates (average 75.6%), structural challenges remain with female manager ratios across all companies in the 4-8% range. Male paternity leave is polarized (over 70% for Keyence and Murata Manufacturing vs. 34% for Kyocera), showing a clear difference between top performers and companies still in the process of improvement.
