Slow-down of Japanese growth in economy and increase of the aged in Japan force us to reexamine a system of social welfare from the financial points of view. Then community care in social welfare will be more important and volunteers have a central role in community activity. Therefore studies of volunteers are necessary to detect latent volunteers and to construct a social system in which people living together help each other. But there are few studies about consciousness of volunteers. This paper intends to quantitatively explain a latent and vague structure in consciousness of volunteers by means of Fuzzy Quantification Theory(Type II)based on fuzzy set theory. Questionnaires which asked female inhabitants in a certain city in Japan are analyzed and characteristic factors that influence them to become a volunteer or not are derived quantitatively.
