A light source apparatus (1) and a projector (100) including the light source apparatus are provided. The light source apparatus (1) comprises: a plurality of light sources each source including a laser diode (12) and a collimating lens (13), said collimating lens (13) collimates a light emitted from said laser diode (12) into an approximately collimated beam, a plurality of housings (10) in which said plurality of light sources are placed so that a light is emitted from each of said light source advances approximately in parallel in the same direction, a condenser lens (20) which condenses lights which is emitted from said plurality of housings (10) to a phosphor (32), a phosphor wheel (30) having said phosphor (32), said phosphor wheel (30) transmitting the lights which is emitted from said condenser lens (20), wherein incident angles of the lights emitted from said housings (10) to an optical axis of said condenser lens (20) are made different by varying mount angles of said housings (10) to a supporting member (60).
