(57) [Problem] To provide an electrode having excellent cycle characteristics that can withstand practical use without losing the characteristic of high energy density of an organic sulfur compound. SOLUTION: A coating layer 1 made of a cation exchange ion exchange resin is provided on a thin film 3 made of an electrode composition containing an organic sulfur compound as an active material. Alternatively, an electrode composition is formed from an electrode composition containing an organic sulfur compound as an active material and a cation exchange ion exchange resin. |
