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.
