摘要： A light source lamp unit (10) includes a light source lamp (11), an ellipsoidal reflector (12) and a plate body (19). The plate body (19) is provided behind the reflector (12) with a gap kept therebetween, which has a shape corresponding to the profile of a reflecting portion (122) of the reflector (12). A cooling channel for passing a cooling air is formed between the plate body (19) and the reflector (12). The width of the cooling channel in a direction along an optical axis of the light source lamp (11) is minimized at a part near a neck portion (121) of the reflecting portion (122) and enlarged toward the peripheral edge of the reflecting portion (122) of the reflector (12).
