摘要：
A cation-exchange membrane using a polyolefin-based substrate with reduced swelling of an ion-exchange resin and a low electrical resistance is provided.
The cation-exchange membrane of the present invention includes a substrate made of polyolefin-based woven fabric, and a sulfonic acid group-containing cation-exchange resin. A portion of the cation-exchange membrane other than the substrate has 23 mass% or more to 35 mass% or less of polyvinyl chloride.
