A cathode film for a battery which has excellent mechanical strength, is easy to handle in a film state, and has excellent ion conductivity, a solid electrolyte composition suitable for the production thereof, and a method for efficiently producing a cathode film for a battery To provide. A polyether polymer, an active material, conductive fine particles, an electrolyte salt compound, and a photopolymerization initiator, wherein the content of the photopolymerization initiator is 2 to 30 parts by weight based on 100 parts by weight of the polyether polymer. The solid electrolyte composition for a cathode, which is a part, is molded and crosslinked by ultraviolet irradiation to obtain a cathode film for a battery. |
