Abstract
A light source device includes: a semiconductor light emitting element (laser element); an optical element that has a plurality of lens regions which are a plurality of divided regions, and that changes an intensity distribution of a light beam emitted from the semiconductor light emitting element, by the plurality of lens regions; and a phosphor element that emits light having, as excitation light, the light which has had the intensity distribution changed by the optical element. The phosphor element is disposed so that a light emitting surface of the phosphor element is inclined with respect to a plane having an optical axis of the excitation light as a normal line, the plurality of lens regions have respective first focal points different from each other, and light beams incident on the plurality of lens regions and focused on the first focal points overlap on the light emitting surface of the phosphor element.
