PROBLEM TO BE SOLVED: To provide an endless metal belt production method by which such a problem that a surface of it becomes too hard can be suppressed.SOLUTION: The endless metal belt production method comprises: a solution treatment step of applying solution treatment to a ring-shaped member obtained by a welding step; a removal step of polishing or grinding a surface of the ring-shaped member to which the solution treatment has been applied, thereby removing a chemical element concentrated layer and oxide layer formed during the solution treatment; and a nitration step of applying nitration to the ring-shaped member which has been subjected to the removal step. In the solution treatment step, a Ti-depletion layer having Ti concentration lower than that of the ring-shaped member before being subjected to the solution treatment, is formed. To the surface of the ring-shaped member subjected to the removal step, the Ti-depletion layer is exposed by removing the chemical element concentrated layer and oxide layer.SELECTED DRAWING: Figure 5 |
