Abstract
Provided is a cation exchange membrane having excellent mechanical strength against folding and the like and capable of delivering stable electrolytic performance for a long time, an electrolysis vessel using the cation exchange membrane and a method for producing the cation exchange membrane. A cation exchange membraneat least includes: a membrane body containing a fluorine-based polymer having an ion-exchange group; and two or more reinforcing core materials arranged approximately in parallel within the membrane body. The membrane body is provided with two or more elution holesformed between the reinforcing core materialsadjacent to each other. In addition, assuming that a distance between the reinforcing core materialsadjacent to each other is represented by a, a distance between the reinforcing core materialsand the elution holesadjacent to each other is represented by b, a distance between the elution holesadjacent to each other is represented by c, and the number of the elution holesformed between the reinforcing core materialsadjacent to each other is represented by n, then a, b, c, and n satisfying the relationship represented by the following expression (1) or expression (2) are at least present./(+1)  (1)/(+1)  (2)
