Abstract: A light source device includes a light source having a light emitting element, a thermal conductor, an optical system housing, and a cooler. The thermal conductor has a first surface and a second surface, and the light source is thermally connected to the first surface. The optical system housing has a mounting part with an opening. The thermal conductor is fixed to the optical system housing in a state that the first surface is disposed in a direction facing the mounting part and the light emitting element is disposed at a position facing the opening. The cooler is thermally connected to the second surface of the thermal conductor and cools heat from the light source.
