Abstract
A light source device includes: a light source which emits light; a first reflector which surrounds a part of the light source and reflects the light emitted from the light source in the direction of an optical axis; and a second reflector which surrounds at least a part of the light source different from the part surrounded by the first reflector and reflects the light emitted from the light source toward the first reflector, wherein the position of a convergence spot of the light reflected by the second reflector is displaced from the position of an emission spot of the light source at least in the direction of a plane perpendicular to the direction of the optical axis.
