Abstract
A disclosed light source apparatus includes a light source including multiple light emitting devices; an optical element configured to transmit light emitted from the light source; a tube configured to hold the optical element; and a tube holder configured to fix the tube by holding an end of the tube close to the light source or by holding the end of the tube on the light emission side away from the light source. A positional displacement preventing member is provided at the other end of the tube on a light emission side away from the light source in such a manner as to be slidable on the tube in the direction of an optical axis and prevent positional displacement of the tube in all directions perpendicular to the optical axis.
