PROBLEM TO BE SOLVED: To provide a method of joining dissimilar metals capable of obtaining a high joining strength by increasing the area of breakage of a facing oxide film on a work surface in joining dissimilar metals by a diffusion bonding method using a friction stirring and joining method, and to provide a dissimilar metal joining method capable of preventing degradation of the joining strength by preventing the reduction of the thickness of a work at a joined portion as much as possible. SOLUTION: In the method of joining dissimilar metals, a second member 2 consisting of a metal different from that of a first member 1 overlaps the first member 1 having recesses 11, 12 from opening part sides of the recesses 11, 12 of the first member 1, and the first member 1 is joined with the second member 2 by pressing the second member 2 against inner faces of the recesses 11, 12 of the first member 1 while stirring the second member by the rotation of a rotary tool 3.
