description | In a winding electrode group a separator and an electrode plate are stacked and wound. A first current collector plate includes a ring member and a partial ring member. The partial ring member is joined, in a first welded part (embodiment), to each of a plurality of first electrode core members arranged in a radial direction of the electrode group. Of a plurality of first welded parts (embodiment), two first welded parts (embodiment) adjacent in the radial direction are disposed at positions shifted in a winding direction intersecting the radial direction. |
