PROBLEM TO BE SOLVED: To provide a polymer electrolyte battery which causes no short- circuiting, having superior load properties, and a high energy density. SOLUTION: In this polymer electrolyte battery comprising a sheet-like positive pole 1, a sheet-like negative electrode 2, and a sheet-like polymer electrolyte layer 3, a finely porous olefin sheet having a large number of fine pores with average pore diameter of 0.5 μm or wider and porosity of 60-80% porosity is used as the supporting body of the polymer electrolyte layer 3. The thickness of the finely porous polyolefin sheet is preferably 25-40 μm. |
