PROBLEM TO BE SOLVED: To provide a joining method capable of reducing adverse influence on joining strength and conductivity of electricity and heat, even if a height of a projection formed on a joint surface for easily removing an oxide film is varied, when removing the oxide film and joining an insert material and a joining object material by eutectic reaction between the insert material and the joining object material, by interposing the insert material between the joint surfaces formed with the oxide film. ! SOLUTION: A projection 1c constituting an uneven structure of the joint surface is formed in an inclined state without erecting on the joint surface. For example, when a shape of the projection 1c is a pyramidal shape, an intersection C with a bottom surface of a perpendicular lowered to a bottom surface from its apex T, is dislocated from the center of gravity G of the bottom surface. !
