This wheel 1 for an automobile is configured in such a manner that a wheel disk 3 includes an outer peripheral ring part 29 having protrusions and recesses, the outer peripheral ring part 29 being formed by continuously and alternately forming a plurality of circular arc-shaped contact parts 25 and a plurality of contactless protrusion parts 22c in the circumferential direction of the wheel, the circular arc-shaped contact parts 25 being in contact with and welded to the bent peripheral part 31 of the wheel rim 2, the contactless protrusion parts 22c protruding further toward the front side than the circular arc-shaped contact parts 25 and separating from the bent peripheral parts 11. Welded parts 35 at which the circular arc-shaped contact parts 25 and the bent peripheral parts 11 are welded together are intermittently arranged in the circumferential direction of the wheel. The configuration provides a large design surface to improve the flexibility of design and improves the rigidity because of the shape effect of the outer peripheral ring part 29 having protrusions and recesses.
