BATTERY MANUFACTURING METHOD AND BATTERY

An integrated plate is configured with a positive electrode plate, a negative electrode plate, and a separator integrated in a card-like shape. The integrated plate comprising a storage part, a positive current collecting part, and a negative current collecting part is formed in an integrated plate manufacturing process. An electrode laminated body is manufactured in a piling process by piling a plurality of the integrated plates such that the storage parts, the positive and negative current collecting parts are overlapped together seen from upper position respectively The integrated plate manufacturing process includes a raising step of forming a raised part raised from other parts 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 plurality of the integrated plates, and the raised parts are overlapped one another seen from upper position in the piling process.
