PURPOSE:To give such shape retainability and strength that strain is seldom produced even if pressure is applied to a film by dissolving a polymer acid salt and high ion-conductive composite in the same solvent, and forming a film with a casting mold by which phase separation of both material is produced. CONSTITUTION:An electrolyte material of the same metal salt as alkali metal salt of the polymer is added to a polymer having an alkali carboxylate group or an alkali sulfonate group in its side chain and polyalkyelene oxide or acryl elastomer to prepare a composite solution. The composite solution is poured in a casting mold in which an organic substance is studded on the mold surface having large surface tension to cast it, then dried under vacuum to form a film. The composite solution is also poured in a casting mold in which a metal vapor deposition film is continuously formed with required gaps kept on the mold surface having small surface tension to cast it, then dried under vacuum. The polymerization degree of the polymer having alkali carboxylate group or alkali sulfonate group in its side chain is 10<2>-10<5>. |
