PROBLEM TO BE SOLVED: To improve the battery characteristics and productivity of a lithium polymer secondary battery to the concentration of a photopolymerization initiator and ultraviolet ray illuminance in the manufacturing method using a precursor solution containing at least one polymerizable monomer, a lithium salt, a nonaqueous solvent, and the photopolymerization initiator initiating polymerization reaction by ultraviolet ray irradiation in the lithium polymer secondary battery using a lithium ion conductive polymer gel placed between a positive electrode and a negative electrode. SOLUTION: In the lithium polymer secondary battery using the lithium ion conductive polymer gel placed between the positive electrode and the negative electrode, the precursor solution containing at least one polymerizable monomer, the lithium salt, the nonaqueous solvent, and the photopolymerization initiator initiating the polymerization reaction by ultraviolet ray irradiation of 500-10,000 ppm is impregnated in the positive electrode, the negative electrode, or the substrate, and it is irradiated the ultraviolet rays having the illuminance stronger than 30 mW/cm<2> in the wavelength of 350-400 nm for 0.1-20 seconds for curing to obtain an electrode layer and a polymer electrolyte which are used for the lithium polymer secondary battery. |
