PROBLEM TO BE SOLVED: To provide a polymer solid electrolyte film and a manufacturing method therefor in which not only excellent ion conductivity is exhibited but also durability such as a swelling-resistant property is simultaneously excellent and it can be preferably used for a proton exchange film of a fuel cell or the like. SOLUTION: After a photo-crosslinkable polymer electrolyte having one or more ionic group and photo-crosslinkable group in the molecule respectively is molded into a film, the thermal crosslinkable group is subjected to crosslinking reaction by a heat treatment to obtain the polymer solid electrolyte film. It is possible that the crosslinking reaction is uniformly carried out even to the inside of the film and the ion conductivity is not reduced by the crosslinking reaction. The polymer solid electrolyte film having excellent ion conductivity and durability can be obtained. COPYRIGHT: (C)2003,JPO
