Abstract
A disk-shaped substrate made of a heat conductive material is provided with, along an outer periphery of one surface of the substrate, a ring-shaped phosphor that emits light by irradiation with blue laser light that is excitation light. The substrate is provided with, on another surface of the substrate, a plurality of convex portions dotting a region corresponding to a region provided with the phosphor. In a phosphor wheel, the substrate is driven by a motor to rotate about an axis of rotation.
