PROBLEM TO BE SOLVED: To provide a laminated secondary cell having electrodes covered by a sack-shaped separator. SOLUTION: For the laminated secondary cell laminating positive electrodes and negative electrodes which are facing each other with a separator laid between, both surfaces of at least one of the positive electrode or the negative electrode are covered by the separator, and the separators are joined to each other by fused joining parts formed at the periphery of the positive electrodes or the negative electrodes. A fused sealing part is formed between the inner peripheral part and the outer peripheral part of the fused joining part, or between adjacent fused joining parts, and an inside part, housing the positive electrode or the negative electrode, and the outer part of the separator, are sealed. |
