Abstract

A light source unit includes light source substrates to emit light, a pair of first members arranged separately from each other, each provided with one light source substrates, a pair of light guide members having an outer circumferential surfaces where the light introduced therein is emitted therethrough, and a pair of second members to hold the pair of respective light guide members. Each of the pair of second members is made of a metal material and includes two projecting portions and an opening formed between the projecting portions where the light emitted from the light guide member passes, and end portions attached to the pair of first members respectively, to receive heat generated from the light source substrate through the first members. The pair of second members are arranged separately from each other forming a void portion therebetween to pass an optical axis of an image capturing device therethrough.
