Abstract
A joint structure includes a first and a second metal member overlapping with each other as viewed in a first direction. The first metal member and the second metal member are joined together. The joint structure includes a welded portion at which the first metal member and the second metal member, overlapping with each other, are partly fused to each other. The welded portion has an outer circumferential edge and a plurality of linear marks. The outer circumferential edge is annular as viewed in the first direction. The plurality of linear marks each extend from an inside of the welded portion toward the outer circumferential edge as viewed in the first direction. Each of the plurality of linear marks is curved to bulge to one sense of an annular direction along the outer circumferential edge.
