Original Abstract Submitted

A method of manufacturing a laminate-type battery is disclosed. The battery includes an electrode body, a side member disposed at a side face of the electrode body, and a laminate film covering the electrode body and a part of the side member, the side member being disposed at a position that is offset to a first side in a longitudinal direction of the side face relative to a center of the side face in the longitudinal direction. The method includes welding the laminate film so as to cover the electrode body and a part of the side member. The side member is shaped such that a thickness of the side member in a transverse direction of the side face increases continuously towards the first side.
