PROBLEM TO BE SOLVED: To provide an oriented ion exchange membrane that stably exhibits greater ionic conductivity than the ionic conductivity which the conventional perfluoro (alkyl)sulfonic acid membrane exhibits by producing a novel ionic conductive polymer having a macrostructure in which a distance between mutual ion exchange groups is short and the ion exchange group itself is oriented by effecting a molecular design of a membrane-forming polymer without mixing other ion exchange resins into the conventional perfluoro(alkyl)sulfonic acid membrane. SOLUTION: A membrane comprises an ion exchanger represented by the formula, wherein the main chains of an aromatic I, a carboxylic II, an oriented group III-based and a storing acid group IV-based chemical bonds are crosslinked by a crosslinking agent and a polymerization degree h is 1-300; a polymerization degree i is 1-400; a polymerization degree j is 1-50; a polymerization degree k is 1-150; a polymerization degree m is 1-40; and a polymerization degree n is 10-1,000. |
