A rotating probe 12 is disposed adjacent to a supporting roller 20. Metallic joining members 1, 2, which are butted or stacked to have a joining portion 3, are disposed between the supporting roller 20 and the probe 12 with one surface of the joining members 1, 2 supported by a circumferential peripheral surface of the supporting roller 12, and the rotating probe 12 is inserted into the joining portion 3 of the joining members 12. Then, the joining members 1, 2 are advanced along the joining portion 3 so that a portion of the joining members 1, 2 where the probe 12 contacts is softened by the friction heat generated due to the rotation of the probe 12 and agitated by the probe 12 to thereby join the joining materials 1, 2.
