PROBLEM TO BE SOLVED: To prevent the leakage of an electrolytic solution caused by damage to a heat-fused part of a laminate sheet. SOLUTION: In each of the heat-fused parts 1c which becomes the longitudinal direction of a laminated battery 1, a protection member 10 is rolled in by the heat-fused part 1c, and the protection member 10 is fixed so that the end 10b is extended from the heat-fused part 1c. The protection member 10 is composed of a cross-sectionally circular rod member, its length L1 is not less than the length L2 of the heat-fused part 1c of the laminate sheet 7, and shorter than the distance L3 between bulkheads 21 of a battery housing case 20.
