Abstract:
1. A conduction path, comprising: a first conductor forming a first conduction path, having a plate shape, made of a first metal, and having a hole; and a second conductor forming a second conduction path, having a plate shape, made of a second metal, and having a press-fit portion press-fitted into the hole, wherein: an inclined bonding surface inclined relative to a normal line of a surface of the first conductor other than the hole, on which a part of the second conductor is overlapped, is formed in a wall surface of the hole and a side surface of the press-fit portion, a bonding portion, at which newly formed surfaces of the hole and the press-fit portion, respectively, are bonded together, is formed in a region located in a periphery of the inclined bonding surface, the newly formed surfaces being surfaces formed by plastic flow caused when the press-fit portion is press-fitted into the hole, at the bonding portion, the first metal and the second metal are integrated with each other and wherein the hole is a through hole.
