A light source apparatus (500) includes an outer casing (12). A light source member and a light source module having a cooling body which cools the light source member are disposed in the outer casing (12). A wind tunnel (10) which surrounds a heat pipe unit (3) as the cooling body of the light source module is provided in the outer casing (12). The wind tunnel (10) includes a wind passage (34) which allows cooling wind to pass through the heat pipe unit (3). An intake-opening (12a) is formed in a surface of the outer casing (12), and cooling wind is taken into the outer casing (12) from outside thereof through the intake-opening (12a). One end of the wind passage (34) of the wind tunnel (10) is connected to the intake-opening (12a). |
