Original Abstract Submitted
A phosphor wheel includes: a substrate including a first principal surface and a second principal surface; a phosphor layer; and a heat dissipating member. The heat dissipating member includes: a projecting portion projecting toward one of the principal surfaces and including (i) a contact surface that contacts the one of the principal surfaces and (ii) a peripheral wall to which the contact surface serves as a bottom surface; and fins provided by cutting and raising regions in a peripheral region of the heat dissipating member excluding a central portion of the heat dissipating member. The projecting portion includes, in the peripheral wall, through-holes provided for ventilation. The projecting portion contacts the substrate via the contact surface to secure a certain distance between the substrate and the heat dissipating member and conduct heat in the substrate to the peripheral region of the heat dissipating member.
