Abstract
There is provided a light source unit which includes an excitation light source configured to emit light in a first wavelength range, a wavelength conversion member on which the light in the first wavelength range is incident from an incident side thereof and which is made up of a member formed to include a luminescent material mixed therein which emits light in a second wavelength range having its wavelength peak on a longer wavelength side than a wavelength peak of the light in the first wavelength range, and a first optical filter which is provided at an output side of the wavelength conversion member which lies opposite to the incident side and which transmits a light component of the light in the second wavelength range which has a wavelength shorter than a third wavelength lying in a wavelength range of the light in the second wavelength range.
