    • PROBLEM TO BE SOLVED: To provide a method for electric diffusion joining, which method can join various metallic members over the whole of the joining surfaces at a low cost without increasing an equipment expense and an operation cost, and further to provide an apparatus for the electric diffusion joining, which apparatus can be suitably applied to the method for the electric diffusion joining.
      SOLUTION: An AC current having a current density of 30 to 1,000 A/cm
      2 per unit area of joining surfaces 11a, 12a is supplied to electrodes 4, 5 while pushing joining members 11, 12 in the butting direction in such a state that the joining members 11, 12 butted to each other are sandwiched between the electrodes 4, 5 via resistors 7, 8. The joining members 11, 12 are diffusedly joined by being heated up to a joining temperature by the total heat caused by the heat generated by the joining members themselves due to the supplied current, the heat generated by the contact resistance between the joining surfaces 11a, 12a, and the heat from both sides due to the heat generation of the resistors 7, 8.
