To avoid adhesion of wear dust produced by braking on a disk wheel, especially on its outside decorative surface.

The disk wheel 12 comprises: a rim 18 on which a tire is mounted; and a disk portion 20 which is provided on one side of the rim 18 and has mounting portions for mounting the disk wheel to a vehicle. The inner circumferential surface 18a of the rim and the reverse surface 16b of a spoke 16 are easily charged with negative electricity, and further are covered by a material in a minus side in the electrification rank than the ornamental surface 20e of the disk portion 20. By this configuration, wear dust much more easily adheres to non-ornamental surfaces than the ornamental surface. As a result, the adhesion of the wear dust to the ornamental surface is suppressed.
