PROBLEM TO BE SOLVED: To provide a light source apparatus capable of suppressing an increase in an incident angle caused by a size of a light emitting part.SOLUTION: A light source apparatus 1 includes a light source 6 and a condensing reflection surface 10 for condensing light from the light source 6 into a condensation position Sa far from the light source 6. The condensing reflection surface 10 includes a plurality of elliptic reflection surfaces 14, 14, ... having mutually different curvature factors in which a center of a light emitting part 7A of the light source 6 is a first focus S1 and a center of the concentration position Sa is a second focus S2, and the respective elliptic reflection surfaces 14, 14, ... are placed in a line so that the curvature factors are increased in accordance with separation from the light emitting part 7A, and in a light component Ha reflected on the elliptic reflection surface 14 separated from the light emitting part 7A, its incident light &thetas; made incident on the condensation position Sa is more reduced. |
