PROBLEM TO BE SOLVED: To provide a complex light guide body and a light source device that suppress flicker or fluctuation of projection light and reduce the light loss.SOLUTION: The complex light guide body includes: a rectangular and cylindrical main light guide body having a reflection surface on its inner surface; and an auxiliary light guide body that is extended inside the main light guide body in the cylinder axis direction so as to partition the inside of the main light guide body, and has reflection surfaces made of reflection films on both surfaces of a flat-plate-shaped light transmissive substrate. The light source device includes: a discharge lamp, a reflector for condensing the light coming from the discharge lamp, and the complex light guide body for guiding the light coming from the reflector. |
