Abstract
A projector includes a light source apparatus, light modulator, projection optical apparatus, exterior enclosure, and heat sink. The light source apparatus includes a substrate having first and second substrate surfaces, light emitters at the side facing the first substrate surface, a frame at the side facing the first substrate surface surrounding the light emitters, and a lid facing the first substrate surface. The light emitters are in an accommodation space formed by the substrate, frame, and lid. The exterior enclosure has a first surface, a second surface that intersects the first surface, and a third surface that intersects the first and second surfaces, and the area of the first surface is greater than the areas of the second and third surfaces. The first or second substrate surface faces the first surface, and the lengthwise direction of the heat dissipation fin extends along the first surface of the exterior enclosure.
