PROBLEM TO BE SOLVED: To provide a new electrolytic cell capable of effectively preventing double-polarization phenomenon. SOLUTION: The electrolytic cell 10 at least part of which is immersed in an electrolyte and which is provided with a partition body 7 for preventing gases respectively generated from an anode 3 and a cathode 5 from being mixed with each other, uses a partition body 7 formed from a metal and forming an insulating passive film 9 of a metal fluoride. The electrolytic cell 10 can prevent the double-polarization phenomenon and provide a high current efficiency by using the insulating passive film 9, which is superior in mechanical strength and hardly causes peeling or deterioration.
