A light source device includes plural solid-state light sources, plural collimator lenses, a collection system, and a fluorescent layer that generates fluorescence from at least a part of the lights from the collection system, wherein at least one anamorphic surface is provided in an optical path from the plural collimator lenses to the fluorescent layer. The plural solid-state light sources are located in positions different from focal positions of the plural collimator lenses in an optical axis direction. |
