摘要： Disclosed is an Al alloy reflective film which has a higher reflectance than that of pure Al films when produced by sputtering, excels in alkali resistance, acid resistance, and moisture resistance, and therefore less suffers from the reduction in reflectance even when a protective coating is not applied. Specifically disclosed is an Al alloy reflective film which contains at least one element selected from Sc, Y, La, Gd, Tb, and Lu in a total amount of from 0.4 to 2.5 atomic percent, with the remainder being Al and inevitable impurities. The Al alloy reflective film has a film surface roughness of 4 nm or less as measured with an atomic force microscope. Also disclosed are an automotive lighting device and an illumination device each provided with the reflective film. Further disclosed is an Al alloy sputtering target for use in the formation of the reflective film.

摘要： Disclosed is a reflective film laminate, which has a pure Ag film or an Ag-based alloy film as a first layer on a base body, and an oxide film of a metal of one or more kinds selected from among Zr, Cr, Nb, Hf, Ta, V, Ni, Mo, W, Al and Si, as a second layer on the first layer. The thickness of the second layer is 0.1 to 10 nm, and deterioration of the reflection ratio of reflective film laminate is 30% or less by having the second layer provided therein. The reflective film laminate is provided with a protection film, which has a high initial reflection ratio, excellent sulfuration resistance and heat resistance, and an extremely small number of pin holes. As a result, the reflection ratio of the reflective film laminate is not easily deteriorated due to aggregation of Ag atoms of the Ag film.
