The punch includes an inner punch portion and an outer punch portion disposed around the inner punch portion, the inner punch portion and outer punch portion are configured to be movable relative to each other, and a depression is formable at a front end of the punch. The joining apparatus is configured such that, in a state in which the depression is formed at the front end of the punch, the punch is moved relatively so as to press and deform the multiple plate members toward the recess by the punch, and the inner punch portion is moved relatively so as to extrude a metal in the depression by the inner punch portion.
