A light source device includes: a first light emitting unit (1) including a light emitting element (1a) that emits light having a predetermined wavelength range; a second light emitting unit (5, 23) including a wavelength conversion member (5b, 23a) that receives the light from the light emitting element (1a) and emits light having a different wavelength range different than the predetermined wavelength range; an optical unit (3) that defines a path of the light emitted from the light emitting element (1a) and a path of the light emitted from the wavelength conversion member (5b, 23a); an air blowing unit (19) that generates a cooling air; and a passage forming member (20a, 20b, 20c) that forms a passage through which the cooling air flows, the passage being in contact with both of the first light emitting unit (1) and the second light emitting unit (5, 23). |
