<p>PROBLEM TO BE SOLVED: To provide a light source device having high optical efficiency, and to provide a projector which can display high-luminance image by means of the light source device.SOLUTION: The light source device is provided that includes a light emitting device 10 for emitting a plurality of light beams including a first light beam LB1 and a second light beam LB2, a collimator lens 20 into which the plurality of light beams enter, a first reflection part 31 into which the first light beam LB1 which the collimator lens 20 has transmitted enters, and a second reflection part 32 into which the second light beam LB2 which the collimator lens 20 has transmitted enters. The first reflection part 31 and the second reflection part 32 are configured in such a way that the first light beam LB1 reflected by the first reflection part 31 passes through a region outside the second reflection part 32 and the second light beam LB2 reflected by the second reflection part 32 passes through a region outside the first reflection part 31, and an angle formed by the first light beam LB1 and the second light beam LB2 is reduced.</p> |
