PROBLEM TO BE SOLVED: To provide a reflective film laminate in which aggregation and sulfurization of Ag hardly occurs. SOLUTION: (1) The reflective film laminate is characterized by that a first layer made of an Ag alloy, which contains Ag as a main component, 0.02 atom% or more of Bi, and totally 0.02 atom% or more of at least one of V, Ge and Zn, and which satisfies following formula (1): 7×[A]+13×[B]≤8, wherein [A] (atom%) is content of at least one of V, Ge and Zn, and [B] (atom%) is content of Bi, is formed on a base body and a second layer made of silicon oxide is formed thereon. (2) In the reflective film laminate, the Ag alloy contains totally 0.1 to 5 atom% of at least one of Au, Pt, Pd and Rh. COPYRIGHT: (C)2009,JPO&INPIT |
