The present invention has an object of providing a bipolar type ion exchange electrolytic cell which is capable of minimizing the anode-cathode distance by a movable system which has a low electric resistance and which is simple and inexpensive, thereby to substantially reduce the electrolysis voltage. The present invention is a bipolar type ion exchange membrane electrolytic cell comprising an anode compartment frame which comprises an anode plate and an anode back plate arranged in substantially parallel with each other with a spacing, conductive anode supporting members arranged with a prescribed spacing from one another between the anode plate and the anode back plate, and a cathode compartment frame which comprises a cathode plate and a cathode back plate arranged in substantially parallel with each other with a spacing, and conductive cathode supporting members arranged with a prescribed spacing from one another between the cathode plate and the cathode back plate, so that the respective back plates are connected back to back to form a compartment frame unit, a plurality of such compartment frame units being arranged with a cation exchange membrane interposed, wherein at least the cathode supporting members comprise a flexible member, and the cathode plate is movably supported by the function of the flexible member.
