Abstract

In a laser welding step, a laser beam is irradiated fin a thickness direction of an external terminal from a side of a front surface of a bus bar toward a space. This irradiation melts a separated portion of the external terminal, i.e., a portion located apart from the insulating part by the space between the insulating part and the separated portion in the thickness direction, and an opposed portion of the bus bar, i.e., a portion opposed to the space via the separated portion in the thickness direction, thereby forming a welded portion including the separated portion and the opposed portion melted together.
