Claim:
1. A light source apparatus comprising: a first light source and a second light source that output light in mutually opposing directions along a single optical axis; a wavelength conversion element that is disposed between the first light source and the second light source and that, upon being irradiated with the light output from the first light source and the second light source, generates light of a wavelength different from that of said light; a first optical member that is disposed between the wavelength conversion element and the first light source, that transmits the light from the first light source, and that, of the light generated in the wavelength conversion element, reflects back light that is scattered towards the first light source, toward the wavelength conversion element, parallel to the optical axis; and a second optical member that is disposed between the wavelength conversion element and the second light source, that transmits the light from the second light source, and that, of the light generated in the wavelength conversion element, deflects, in a direction intersecting the optical axis, the light scattered toward the second light source and the light reflected back by the first optical member.
