Abstract

See full text

The present invention provides an anion exchange membrane that has low electrical resistance when used in electrodialysis, is produced without an increase in cost, and is excellent in selective permeability to monovalent anions, and a method for producing the same. The anion exchange membrane has a tertiary amino group and a quaternary ammonium group as functional groups, such that an intensity ratio of the tertiary amino group to the quaternary ammonium group is 1.0 or more as measured by X-ray photoelectron spectroscopy on a surface of the anion exchange membrane having the tertiary amino group and the quaternary ammonium group as the functional groups.
