This paper examines time use of the participants in voluntary activities. I conducted a time budget survey to the participants in voluntary activities during November 2000 through January 2001 and got 84 participants' data. Female participants spend more time on voluntary activities than male participants. Employed males devoted less time to voluntary activities. Single participants spend more time on voluntary activities than married participants. Males participate in voluntary activities on weekday night and daytime of weekend. Females participate in voluntary activities on daytime of both weekday and weekend. The effect of gender on the housework is also found in the participants in voluntary activities. Married females have long housework time and take the higher share in housework. However, the male participants in voluntary activities are engaged in housework more and disagree with the traditional view of gender role more than non participant males.
