PROBLEM TO BE SOLVED: To more highly accurately hold the emission angle of a light beam.SOLUTION: A light source device includes a light source 11 emitting laser light, a light source holder 21 having a positioning part 21a coming into contact with a plane part 11a provided in the light source 11 and being orthogonal to the emission direction of the laser light, to position the light source 11, an intermediate member 31 coming into contact with the light source 11, and a leaf spring 22 energizing the light source 11, so as to press the light source 11 against the positioning part 21a through the intermediate member 31. A plane where the plane part 11a and the positioning part 21a come into contact with each other and a contact part where the leaf spring 22 and the intermediate member 31 come into contact with each other are located on one and the same plane. |
