摘要：
A light source unit is provided, which includes a light source with a plurality of light emission portions two-dimensionally arranged; a substrate on which the light source is mounted; a first support portion supporting the substrate; a bias member biasing the substrate towards the first support portion; a coupling element coupling a light beam emitted from the light source; a second support portion supporting the coupling element; a holding member holding a position of the substrate relative to the first support portion, a fitting portion provided in each of the first and second support portions to rotatably fit the first and second support portions into each other around an optical axis of the light source; and a fastening member integrally fastening the first and second support portions.
