Abstract
An electrolyte membrane having a structure wherein fine rubber particles having substantially no ion-conducting group and having an average particle size of 20 nm to 1 μm are uniformly dispersed in a matrix including a resin component having ion-conducting group. The electrolyte membrane has high bonding ability to electrodes and does not cause cracks and ruptures because it is kept flexible even under low humid or absolutely dried condition, in addition, shows high ion conductivity even under low humid or absolutely dried condition because the matrix having ion-conducting groups are continuous.
