Zusammenfassung:	To provide a light source device which is superior in uniformity of illuminance of irradiation light.SOLUTION: A light source device (11) according to the present invention has a light source (20) having a plurality of light emission parts (21), and a projection optical system (15) for irradiation with light that the light source emits, a light emission quantity per unit area of a light emission region of the light source corresponding to an irradiation region relatively large in enlargement rate of the projection optical system being larger than that of a light emission region of the light source corresponding to an irradiation region relatively small in enlargement rate of the projection optical system.SELECTED DRAWING: Figure 7 【課題】照射される光の照度の均一性に優れる光源装置を提供する。【解決手段】本発明の光源装置（１１）は、複数の発光部（２１）を備える光源（２０）と、光源で発した光を照射する投光光学系（１５）とを有し、投光光学系の拡大率が相対的に大きい照射領域に対応する光源の発光領域の単位面積あたりの発光光量が、投光光学系の拡大率が相対的に小さい照射領域に対応する光源の発光領域の単位面積あたりの発光光量よりも大きいことを特徴とする。【選択図】図７
