PROBLEM TO BE SOLVED: To prevent active material falling off from an electrode plate from flying out and, at the same time, to prevent wrinkle occurred at coupling of separator sheets. SOLUTION: A positive electrode plate 12 of a laminated secondary cell is contained in a bag-like separator 13, which is made in a bag shape by coupling two separators at their outer edge parts. The bag-like separator 13 has a plurality of notches 15 formed reaching a position not overlapping with the positive electrode plate 12 going across a junction part 14 of the separators. |
