This research was done to see the relevance between leader experience and self-concept of group leader. The hypothesis was there should be similar experience between the leaders sharing the similar self-concept (classifying self-concept into individual self, relational self, and collective self). Participants were university students who have experienced group leader for a year. Interview and LSCS questionnaire was used for the experiment. As a result, the following pairs of experience and self-concept were related: object of leader feeling negative emotion and individual self, types of negative emotion leader felt and individual/ relational self, positive feedback and relational self, cognition of group characteristic and collective self. Lastly, essential experience factors for serving leaders were found in the research.
