Abstract
A battery producible with high quality and at low costs by decreasing the output of an energy beam used to weld multiple current collecting tabs to an outer case and thus securing the sufficient margin of the output thereof. An aspect of the battery includes an overlapping part K of multiple current collecting tabs connected to a negative electrode of an electrode body being welded to an outer case via a weld group, and the weld group includes a weld part and weld part that are each in the form of a line when they are viewed from the outside of the outer case. The weld as a first weld serves to weld the outer case to all of the multiple current collecting tabs, and the weld as a second weld serves to weld the outer case to only one or some of the multiple current collecting tabs.
