According to the present invention, there is provided an ion exchange membrane produced by using a polymerizable composition for forming an ion exchange resin precursor, applying the polymerizable composition to a polyolefin-based filament base material, and then polymerizing the composition , after forming an ion-exchange resin precursor, the polymerizable composition for forming an ion-exchange resin precursor containing a monomer component and a 100 parts by mass of polyethylene particles having 50 to 120 parts by mass, the monomer component contains an aromatic monomer for introducing an ion exchange group and a nitrogen-containing aliphatic monomer, and the nitrogen-containing aliphatic monomer is 10-35 parts by mass. The amount of mass % is present in the aforementioned monomer components. |
