Abstract: A light source according to the present invention includes an excitation light source configured to emit excitation light, and a luminescent wheel including a base material, a fluorescent light emitting zone formed on one surface of the base material and configured to emit fluorescent light having a wavelength in a wavelength range which differs from that of the excitation light and a reflection zone disposed so as to be aligned with the fluorescent light emitting zone on the one side surface of the base material and configured to reflect the excitation light, and a shining position of the excitation light on the fluorescent light emitting zone and a shining position of the excitation light on the reflection zone differ from each other in relation to a radial direction of the luminescent wheel.
