PROBLEM TO BE SOLVED: To provide a conductive, elastic composition which holds sufficiently a resistance to solvents, a film formability, and a burrier property, by which an energy-accumulating component of such as electric double-layer capacitor can be downsized, is given a large capacitor, and is endowed with high reliability. SOLUTION: A conductive material consisting of a styrene elastomer (block copolymer of styrene-etylene) and carbon is used for making the elastic material. The styrene elastomer has block structure of styrene-etylene-propylene-styrene and its molecular weight is 100,000-300,000. A polysiloxane of 0.5-2.0 pts.wt. (preferably 0.5-1.0 pts.wt.) containing carboxyl is used as an additive of the conductive material. COPYRIGHT: (C)2004,JPO
