Abstract
A light source device includes: a light-emitting part; a light guide including in its center a columnar part whose central axis direction is a lengthwise direction, that guides light input into an end face from the light-emitting part, and outputs light from a side face of the columnar part; a light guide holder that covers an end of the light guide except for at least part of the end face; and a support part, including a through-hole that penetrates from one face to another face formed therein, that holds an end of the light guide holder on a side of a first opening on the one face of the through-hole so as to allow sliding in the lengthwise direction, and light is input into the light guide via a second opening on the other face of the through-hole.
