Abstract
An ion exchange membrane of the present invention contains a resin having an amino group and a constitutional unit represented by Formula 1, in which the number of amino groups per dry mass is 0.15 to 2.4 mmol/g. In Formula 1, L1 represents an alkylene group or an alkenylene group, Ra, Rb, Rc, and Rd each independently represent an alkyl group or an aryl group, Ra and Rb and/or Rc and Rd may form a ring by being bonded to each other, n1 and n2 each independently represent an integer of 1 to 10, and X1− and X2− each independently represent an organic or inorganic anion.
