To provide a production method where an electrochemical element capable of directly collecting current from an anode and a cathode while highly holding current efficiency is obtained without using an electrode base material, and also, the electrochemical element can be efficiently produced.
The solid high polymer electrolyte 4 is composed of two solid high polymer electrolytic membranes, and, for increasing the electric resistance of the extension part 41 therein, includes an electrically insulating film 5 between the two solid high polymer electrolytic membranes. Since the electrically insulating film 5 shields or at least reduces the electric current flowing through a non-electrolyzing region 6, high current efficiency can be held even in an electrolyzing region 7 even without using an electrode base material used in the conventional technique. Further, the electrically insulating film 5 has a film width at which the tip part enters a part of the electrolyzing region 7.
