Abstract
Environmental problems should be tackled immediately as our own problems rather than global issues. The problems mix up "economy", " society", and "environment" in a complex way. However, if a consumer who should take them in is disregarded, it is difficult to expect his/her motivated actions. Based on this understanding, conduct codes to realize an environmental conscious society embedded in each artifact must be proposed. In this research, we analyze customer's subjective determinant in flea market, and will discuss an approach for realizing reuse of the product and the conduct codes.
