A light source device, having an excellent cooling efficiency and usable when multiple devices are stacked in a vertical direction, is presented. The light source device includes a casing having a sufficiently small size in height relative to depth and width, wherein, an intake hole is formed in a casing wall for taking in air and an exhaust hole is formed for exhausting air, a fan arranged inside the casing so that a rotating shaft thereof is inclined with respect to the height direction of the casing and partitioning the interior into front and rear chambers to form an air flow from the intake hole to the exhaust hole, a light source inside the front chamber, and a heat radiation fin provided thermally connected to the light source inside the front chamber, wherein the intake hole is in the front chamber and the exhaust hole is in the rear. |
