A light source apparatus 1 comprising: a plurality of light sources 10 each including a laser diode 12 and a collimating lens 13 which corresponds to said laser diode 12, a condenser lens 20 which condenses lights emitted from said light sources 10,and a phosphor wheel 30 having a phosphor 32, said phosphor wheel 30 transmitting a light which is emitted from said condenser lens 20, wherein at least in a part of said plurality of light sources 10, said collimating lens 13 and said laser diode 12 are placed with a first shift such that an optical axis of said collimating lens 13 is shifted from an optical axis of a light emitted from said laser diode 12 in the direction perpendicular to the optical axis of the emitted light 12, wherein said laser diodes 12 include a first laser diode 12A in which a direction of a short axis of a condensed shape thereof is placed in a first direction, and a second laser diode 12B in which a direction of a short axis of a condensed shape thereof is placed in a second direction which is different from the first direction, and wherein said collimating lens 13 which corresponds to said first laser diode 12A and said collimating lens 13 which corresponds to said second laser diode 12B are placed with a second shift in a direction of the optical axis of said collimating lens 13. |
