Abstract
A light source device includes: an arc tube having a light emission portion; a first reflection mirror having a substantially concave surface for reflecting light emitted from the light emission portion; and a container which accommodates the arc tube and the first reflection mirror, wherein the container has a duct unit disposed above the arc tube. The duct unit includes a first opening open to the arc tube and disposed at a position shifted toward the traveling direction side from an opening end of the first reflection mirror, a wall portion which forms the edge of the first opening on the side opposite to the traveling direction side as a final end of the duct unit, and an inclined portion disposed in the vicinity of the edge of the first opening on the traveling direction side to bend the flowing direction of the cooling air toward the surface opposite to the surface having the first opening.
