PROBLEM TO BE SOLVED: To provide a method for manufacturing a joined body capable of obtaining a joined body in which an aluminum member and a metal component formed of one of copper, nickel and silver are favorably joined to each other, and when a heat cycle is loaded, occurrence of a crack in a junction can be suppressed, and joint reliability is favorable.SOLUTION: There is provided a method for manufacturing a joined body 12 in which an aluminum member 22A formed of aluminum, and a metal member 22B formed of copper, nickel or silver are joined to each other. An Si concentration on a junction surface of the aluminum member 22A is set to be within a range of 0.03 mass% or more and 1.0 mass% or less, a Ti material 25 is interposed between the aluminum member 22A and the metal member 22B, the aluminum member 22A and the metal member 22B are laminated, the laminated aluminum member 22A and metal member 22B are heated, and each of the aluminum member 22A and the Ti material 25, and each of the Ti material 25 and the metal member 22B are solid-phase diffusion bonded to each other.SELECTED DRAWING: Figure 5 |
