PROBLEM TO BE SOLVED: To provide a reflector which is made thin, and efficiently propagates light to a surface to be irradiated, and a light source device and a projector using the same. SOLUTION: The reflector 12 is installed around the central axis AX on which a light emitting part 13 to emit light is disposed, in combination with the light emitting part 13, and includes a curved surface reflecting part 16 which includes nearly the same shape as a curved surface of revolution centered on the central axis AX and reflects light from the light emitting part 13, and a first plane deflecting part 14 and a second plane deflecting part 15 which are formed as planes located on the central axis AX sides relative to the curved surface of revolution and deflect light from the light emitting part 13 forward. The plane deflecting parts have a plurality of structures formed on the planes. COPYRIGHT: (C)2009,JPO&INPIT
