PROBLEM TO BE SOLVED: To improve productivity by energizing while abutting both tapered faces each other and pressurizing so as to reduce a time required for joining. SOLUTION: Tapered faces 1a, 2a of a pair of female/male are formed to conductive and different kind materials to be joined 1, 2. A thin insert material 3 of plating, etc., is stuck to the tapered face 1a of the material 1 to be joined. By pressurizing while the tapered faces 1a, 2a of the materials 1, 2 to be joined are abutted and by energizing, a boundary is heated/activated to execute joining. A pair of female/male tapered faces can be formed to two steps. Also, One tapered face at least of a pair of female/male is arranged with a contact part to have line contact as viewing from the circumference. Further, a contact face having face contact as viewing from the circumference is formed to one tapered face at least of a pair of female/male. By this method, the materials to be joined have joining strength equivalent to that of base material strength. |
