Method for manufacturing electrode for electric power storage module, and method for manufacturing electric power storage module

Abstract

This method for manufacturing an electrode 4 for an electric power storage module comprises: a disposing step of disposing, along an outer edge portion 42c of an electrode foil 42, a first resin member 45 on a first surface 42a and a second resin member 46 on a second surface 42b; a temporary fixing step of temporarily fixing each of the first resin member 45 and the second resin member 46 to the electrode foil 42 by point welding using heat irons 81, 82; and a main welding step of thermally welding each of the first resin member 45 and the second resin member 46 to the electrode foil 42, wherein, in the temporary fixing step, a pressing member is disposed on at least one side of the first resin member 45 and the second resin member 46 in a wider range than tip portions 81a, 82a of the heat irons 81, 82, and the first resin member and the second resin member are point-welded to the electrode foil 42 in a state where the resin member around the welding point is pressed by the pressing member.
