Abstract
A light source device () has: a light-emitting tube () including a light-emitting portion () that emits a light beam through electrodes () and a pair of sealing portions () provided on both sides of the light-emitting portion () and lead wires () for making electrical continuity between the electrodes () and an external power source, the lead wires () extending from the distal ends of the sealing portions (), respectively; and a reflector () having a concave reflecting surface () that emits, from the opening thereof, the light beam irradiated by the light-emitting tube () after aligning in a predetermined direction, in which the lead wire () extends from the sealing portion () on the light beam irradiation front side of the reflector () up to the opening end portion () of the reflector (), the lead wire () having bent portions () in which the lead wire () is sequentially bent along the shape of the opening edge portion (). The lead wire () is reliably fixed to the reflector () by the spring force between the bent portions ().
