Abstract
An object of the present invention is to improve the efficiency of heat dissipation from a phosphor wheel while suppressing the air resistance and noise of the phosphor wheel during the driving of a light source apparatus. A phosphor wheel (100) according to the present invention includes: a disc-like substrate (120); a phosphor layer (130) formed on the substrate; and a plurality of heat dissipation fins (154a, 154b, and 154c) overlapping with each other when viewed in a direction orthogonal to a surface of the substrate.
