Abstract
The composite anion exchange membrane includes: a surface layer on a single surface or both surfaces of an anion exchange membrane substrate, in which the above-described surface layer contains a copolymer of a monomer A which is a water-soluble polyfunctional monomer and a monomer B which is a cationic monomer, an anion exchange capacity of the above-described surface layer is 0.05 meq/cmto 0.50 meq/cm, and an anion exchange capacity of the above-described anion exchange membrane substrate is 1.0 meq/cmto 5.0 meq/cm.
