Abstract
The invention provides an ion exchange membrane electrolytic process unlikely to undergo any current density drop even when brine having a concentration lower than usual. Electrolysis occurs while the concentration of an aqueous solution of an alkaline metal chloride in an anode chamber partitioned by a cation exchange membrane is set at 2.7 mol/l to 3.3 mol/l, and a gap is provided between the cation exchange membrane and the anode.
