description	According to one embodiment, a secondary battery includes an outer container with a lid, an electrode body stored in the outer container and including an electrode group, a positive electrode current collecting tab group and a negative electrode current collecting tab group, output terminals on the lid, a positive electrode lead, and a negative electrode lead. A second joint portion of the electrode leads has a first joint surface and a second joint surface opposing each other. A part of current collector tab groups of the same polarity is joined to the first joint surface, and another part of the group of current collector tabs of the same polarity is joined to the second joint surface and opposing the part of the current collector tab groups across the second joint portion.
