Abstract
To provide an ion exchange membrane for alkali chloride electrolysis which has a low membrane resistance and which is capable of reducing the electrolysis voltage during the alkali chloride electrolysis, while increasing the membrane strength. An ion exchange membranefor alkali chloride electrolysis wherein a reinforcing materialobtained by weaving with reinforcing yarnsand sacrificial yarnsis embedded in a fluoropolymer having ion exchange groups, the ion exchange membranecomprises elution holes () formed by eluting at least a portion of a material of the sacrificial yarns, and in a cross section perpendicular to the length direction of the yarns, the total area (S) obtained by adding the cross-sectional area of an elution holeand the cross-sectional area of a sacrificial yarnremaining in the elution holeis from 500 to 1,200 μm, and the number (n) of elution holesbetween adjacent reinforcing yarnsis at least 10.
