PROBLEM TO BE SOLVED: To provide a method for bonding metals of a different hardness, the method by which a large bonding strength can be obtained. SOLUTION: The diffusion bonding method is used for bonding a first member 110 formed using a first metal and a second member 120 formed using a second metal that has a higher harness than the first metal. The method comprises a process of removing an oxidized film formed at least on one bonding face by sliding the bonding face 112 of the first member and that 126 of the second member, and a process of bonding the first and second members by making an electric current flow between them while imparting a pressing force thereto.
