PROBLEM TO BE SOLVED: To provide a polymer battery with excellent cycle property and high productivity by improving compatibility with a monomer-containing mixed solution of a core material of an electrolytic sheet in gel state (that is, a mixed solution of an electrolytic solution and low molecular weight liquid-phase monomer becoming electrolytic solution holding material of the electrolytic sheet in gel state by polymerization) without deteriorating the cycle property. SOLUTION: In this polymer battery comprising a sheet-like positive electrode 1, sheet-like negative electrode 2, and a gel electrolytic substance sheet, a porous polyolefin sheet surface-treated in gas phase is used as the core material of the gel electrolytic sheet 3. Plasma treatment, corona discharge treatment, sputtering etching, electron beam radiation, ultraviolet radiation, radioactive ray radiation, etc., are preferably employed for the method of gas phase surface treatment of the porous polyolefin sheet 3. |
