The phosphor wheel has: a disc-shaped substrate; and a phosphor disposed on one surface of the substrate in a circumferential direction. The motor rotatably drives the phosphor wheel. The plurality of blades are fixed to the other surface of the substrate so as to be integrally rotated with the phosphor wheel, and extend in a radial direction of the phosphor wheel from an axis of rotation of the motor.
