PROBLEM TO BE SOLVED: To provide a manufacturing method of a joined article by press-fit joining that prevents swelling of a joined article related to the press-fit joining and is excellent in precision, quality, and reliability, and provide the joined article.SOLUTION: A manufacturing method of a joined article comprises the steps of: heating and softening a junction of both members by primarily energizing both the members to press an insertion part into a hole of a first member with pressure applied by an upper electrode; performing press-fit joining by solid-phase diffusion by pressing the insertion part of a second member into the hole until pressure applied by a pressing part of the upper electrode when moving the upper electrode downward can be applied on the lower electrode via a color member and the first member; after stopping the primary energization, performing heat treatment by secondary energization such that both the members are secondarily energized with pressure applied by the upper electrode, and the secondary energization is stopped after heating the junction between both the members and its vicinity.SELECTED DRAWING: Figure 1 |
