PROBLEM TO BE SOLVED: To provide a manufacturing method for polymer electrolyte secondary battery, which can impregnate a laminate quickly with a non-aqueous electrolytic solution and can increase the solution retaining capacity. SOLUTION: A polymer electrolyte secondary battery concerned is embodied as a laminate consisting of a positive electrode containing polymer to retain non-aqueous electrolytic solution and an active material, a solid polymer electrolyte layer containing polymer to retain non-aqueous electrolytic solution, and a negative electrode which contains polymer retaining non-aqueous electrolytic solution and a carbonaceous material to occlude and release lithium ions. The laminate is accommodated in a vessel, the inside is decompressed, and non- aqueous electrolytic solution is injected into the laminate placed in the vessel, and thereby the laminate is impregnated with the electrolytic solution. |
