PURPOSE:To prevent short circuit caused by positioning error by piling positive active materials themselves or negative active materials themselves an insulating sheet inserted between them. CONSTITUTION:An insulating sheet 40 is put on a pair of positive electrode 31 and negative electrode 32 or a pair of positive electrode 33 and negative electrode 34, and a case 35 is folded with the insulating sheet inserted so that positive electrodes 31, 33, negative electrodes 32, 34, and electrolytes 36, 37 are faced each other, then the edge of the case 35 is sealed. By the insertion of the insulating sheet 40 between the active materials 31, 33 themselves or the negative active materials 32, 34 themselves when they are piled, short circuit caused by positioning error can be prevented. |
