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 a contact surface that contacts the one of the principal surfaces; 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 regions each include a notch provided by cutting off part of a first side of the region opposite to a second side of the region continuous with a corresponding one of the fins. The projecting portion secures a certain distance between the substrate and the heat dissipating member and conducts heat in the substrate to the peripheral region of the heat dissipating member.
