Abstract: An anion-exchange membrane of the present invention includes a substrate made of polyolefin-based woven fabric and an anion-exchange resin, and has an electrical resistance measured using 0.5 M NaCl solution at 25° C. of 1.0 Ω•cm2 or more to 2.5 Ω•cm2 or less, a bursting strength of 0.7 MPa or more to 1.2 MPa or less, a water permeation rate measured using pressured water at 0.1 MPa of 300 ml/(m2•hr) or less, a thickness of the substrate of 90 µm or more to 160 µm or less, and an open area ratio of the substrate of 35% or more to 55% or less.
