PROBLEM TO BE SOLVED: To provide a method for manufacturing a protective element which has large adhesion strength, between a polymer and an electrode and has a small resistance value at room temperature. SOLUTION: Forty-five to 55 vol.% of crystalline high molecular polymer and 45-55 vol.% of conductive filler are kneaded and formed into a sheet to obtain a molding. The molding is etched on its surface, and then an electrode is formed on the surface of the molding through sputtering or evaporation. Thereafter, pressure is applied to the electrode of the molding at a temperature which is not lower than a crystallization temperature of the crystalline high molecular polymer.
