Clay working as a popular activity is not only easily to be participated in without qualification requirement but also to touch the intrinsic value of human being. Based on the approach of means-end chain (MEC), this research analyzed the clay-workers intrinsic value through the method of laddering semi-structure interviews. The results revealed the deepest intrinsic values of clay-workers, including happiness, romance, decreased depression, spiritual sustenance, self-fulfillment, social skill, and health improvement. Distinguished by the various characters of clay-workers, those intrinsic values of the males mainly focus on decreasing depression, while the females tend to seek happiness and romance; serious participators tend to pursue a sense of self-fulfillment; and mild participators tend to look for happiness and romance. Concluding this research, clay working can provide multiple leisure characteristics but gradually form the intrinsic values of the clay-workers as well.
