In a light source apparatus according to the present invention, variation does not occur depending on an operator, and further it is possible to adjust the position of a discharge lamp even after the light source apparatus is installed in a case. The light source apparatus has a discharge lamp and a reflection mirror which are disposed in a casing, and light emitted from the discharge lamp is condensed by the reflection mirror to an end portion of an integrator lens disposed outside the casing. Further, the light source apparatus comprises a position adjustment unit in which position of the discharge lamp is adjusted so that a target for lamp position adjustment formed on the casing is seen on a virtual line which passes at least one through-hole for inspection provided in the reflection mirror and a portion where a luminescent spot of the discharge lamp is formed.
