PROBLEM TO BE SOLVED: To uniformize each light intensity distribution emitted by a plurality of semiconductor light emitting devices. SOLUTION: A light source device 10A comprises a printed circuit board 11 with a through hole 11a penetrated therein; the plurality of semiconductor light emitting devices 12 that are attached centering around a hole 11a in one surface 11b of the printed circuit board 11; a light integrator 15 that is fitted in the hole 11a of the printed circuit board 11, and has a light incidence end 11c protruded to one surface 11b side of the printed circuit board 11 and also has a light emission end 11d protruded to other surface 11c side of the printed circuit board 11; a plurality of condenser lenses 16 which are arranged opposite to the plurality of semiconductor light emitting devices 12, respectively, for converting each light emitted from the plurality of semiconductor light emitting devices 12 into parallel light; and a reflection condensing mirror 17, which are arranged opposite to the plurality of condenser lens 16, and which reflects back each parallel light from the plurality of condenser lens 16 for condensing in the vicinity of a light incidence end 15c of the light integrator 15.
