PROBLEM TO BE SOLVED: To provide a solid state welding method of metallic members, a method in which a weld zone of metallic members is intensively heated using a millimeter wave and in which the metallic members are prepared for diffusion welding to each other without heating the entire metallic members at high temperature. SOLUTION: Metallic members W, W' are covered with an heat insulating material 9. Also, a part within a prescribed range from a welding face between the metallic members W, W' is made a part Wa to be heated, and then, the part of the heat insulation material 9 deviated from the part Wa to be heated is covered with a metallic cover 10 of a high thermal conductivity. Thereafter, the metallic members W, W' are brought into pressurized contact with each other in a manner causing no plastic deformation, with the millimeter wave radiated in such a state to heat the part Wa to be heated.
