METAL JOINTED BODY, SEMICONDUCTOR DEVICE, WAVE GUIDE TUBE, AND METHOD FOR JOINING MEMBERS TO BE JOINED

Provided is a metal jointed body, joined by solid-phase joining in the atmosphere, in which no protrusion of molten joining material occurs, that improves dimensional stability. A metal jointed body is formed by (A) making Ag films of two metal laminated bodies opposed to each other, the metal jointed body being configured by sequentially laminating a Zn film and an Ag film on an Al substrate serving as a member to be joined, and (B) bringing the Ag films into contact with each other, then (C) heating is performed while pressurizing, and closely adhering and solid-phase joining the Ag films to each other. The completed metal jointed body is a portion where Al—Ag alloy layers are provided on both sides of an Ag—Zn—Al alloy layer to join the Al substrates to each other.
