Abstract: A light source unit includes a plurality of light sources emitting light for irradiating an object, and a holding portion holding the plurality of light sources having an insertion hole for an optical fiber inserted therethrough to propagate the light from the object formed therein. The holding portion holds each of the plurality of light sources such that an irradiation region of the light of each of the plurality of light sources is formed on one side of the holding portion. The insertion hole has a first opening that is an opening facing the irradiation region and a second opening that is an opening different from the first opening, and is formed in the holding portion such that one end surface of the optical fiber is exposed from the first opening and faces the irradiation region when the optical fiber is inserted therethrough.
