Provided are a method for producing an anion exchange resin which is capable of producing an electrolyte membrane with excellent mechanical property (strength). A monomer for forming a hydrophobic group is reacted with a monomer for forming a hydrophilic group in the presence of bis(1,5-cyclooctadiene)nickel(0) as a catalyst, 2,2-bipyridine as a co-ligand, a bromide or an iodide as a co-catalyst, and a reducing agent to produce an anion exchange resin where the hydrophobic group is connected to the hydrophilic group via direct bond, in which a mole number of bis(1,5-cyclooctadiene)nickel(0) is 0.3 to 1.8 times a total mole number of the monomer for forming a hydrophobic group and the monomer for forming a hydrophilic group.
