Battery

A battery comprising:

• an electrode body;
• a plurality of current collector tabs extending from a side surface portion of the electrode body;
• a current collector terminal connected to the current collector tabs;
• and
• a laminate film housing the electrode body and the current collector tabs, wherein:
• each of the current collector tabs includes a root portion that is an end portion on the electrode body side, a connection portion for connecting to the current collector terminal, and an intermediate portion connecting the root portion and the connection portion;
• the current collector tabs include a laminated connection portion in which the respective connection portions of the current collector tabs are laminated in a thickness direction;
• the current collector terminal includes an inner surface facing the side surface portion of the electrode body, and a side surface disposed along an outer edge of the inner surface;
• the laminate film is disposed on the side surface of the current collector terminal;
• a main surface of the laminated connection portion is joined to the inner surface;
• and
• a spacer member is disposed between the inner surface and the side surface portion.
