Battery manufacturing method and battery

A manufacturing method of a battery comprising an electrode laminated body encased in an outer casing, the electrode laminated body being formed by piling a positive electrode plate, a negative electrode plate, and a separator, including

• an integrated plate manufacturing process of manufacturing an integrated plate configured with the positive electrode plate, the negative electrode plate, and the separator which are integrated in a card-like shape, the integrated plate comprising a storage part including the positive electrode plate, the negative electrode plate, and the separator, a positive current collecting part including the positive electrode plate only, and a negative current collecting part including the negative electrode plate only, and
• a piling process of manufacturing the electrode laminated body by piling a plurality of the integrated plates such that the storage parts, the positive current collecting parts, and the negative current collecting parts are overlapped together seen from upper position respectively, wherein
• the integrated plate manufacturing process includes a raising step of forming a raised part raised from the other part by partly bending or curving in at least a coinciding one of the positive current collecting part and the negative current collecting part for the integrated plate, and
• a plurality of the raised parts are overlapped one another seen from upper position in the piling process.
