PROBLEM TO BE SOLVED: To provide a press fit joining method and press fit joining component excellent in mass production property, reliability, and strength wherein the joining is easily performed under the good environment in press fitting of mutual members composing metal element component. SOLUTION: While a first member 2 is disposed on the surface part of a first electrode 6, the side surface part 12 of a second member 4 is mechanically held by a second electrode 8 composed of a plurality of electrode pieces 9 by using the first member 2 having a hole part 3 where the same inner wall surface part is formed for the cross section of the press fit part, and the shaft like second member 4 where a predetermined press fit allowance is provided between the first member 2 and the hole part 3. The second member 4 held toward in the hole part 3 of the first member 2 is pressed by a predetermined pressure and an electric resistance heat is generated at both joining parts by energizing between the two members. The second member 4 is press fitted in the hole part 3 and a joining boundary surface is formed at the joining part between the joining surface part of the second member 4 and the inner wall surface part of the hole part. The joining is made to be the joining in a solid phase state. COPYRIGHT: (C)2007,JPO&INPIT
