Abstract
An overlapping part of a first member and a second member is joined using a tool for friction stir spot welding and a rivet. The first member is disposed on a side where the tool is press-fitted first, and the second member is disposed on a side where the tool is press-fitted last, so that the overlapping part is formed. The tool is press-fitted into the overlapping part to perform friction stirring, thereby forming a friction stirred part in the overlapping part. The rivet is press-fitted into the friction stirred part from the first member side.
