Abstract: Provided is an Al alloy reflective film which does not require a protective film in that it has excellent alkali resistance (resistance to alkali corrosion), acid resistance (resistance to acid corrosion) and humidity resistance (resistance to a high-temperature, humid environment) even if there is no protective film, and which contains 2.5 to 20 at % of at least one element selected from Gd, La, Y, Sc, Tb, Lu, Pr, Nd, Pm, Ce, Dy, Ho, Er, and Tm, with the balance being Al and inevitable impurities. Also provided are an automobile light, illuminator, and ornamentation having such an Al alloy reflective film. Further provided is an Al alloy sputtering target, which is for forming such an Al alloy reflective film and which contains 2.5 to 35 at % of at least one element selected from Gd, La, Y, Sc, Tb, Lu, Pr, Nd, Pm, Ce, Dy, Ho, Er, and Tm, with the balance being Al and inevitable impurities.
