Original Abstract Submitted
A power storage device includes a flat wound electrode body, a case, and a positive terminal ultrasonically welded to a positive current collecting part of the electrode body. A surface-welded portion of a welded portion formed on a laminated current collecting part of the positive current collecting part has an outer periphery including an inner side, an outer side, a closer side and a far side. An outside close endpoint of the outer side is positioned on one side toward a reference position in an electrode widthwise direction with respect to an inside close endpoint of the inner side, and the closer side forms a straight line or a line passing through a region farther from the reference position than the straight line.
