REFLECTION MEMBER AND METHOD FOR MANUFACTURING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a reflection member in which an aluminium film is provided on a substrate and that has a high reflectance in an ultraviolet region, and a method for manufacturing the same.SOLUTION: A reflection member 1 includes a substrate 2 and an aluminum film 3 provided on the substrate 2. The aluminum film 2 has a crystallite size of 18 nm or more that is obtained by an integral width of an X-ray diffraction peak by a crystal surface (111) of a cubic crystal aluminum.SELECTED DRAWING: Figure 1
