PROBLEM TO BE SOLVED: To provide a method for manufacturing a curved mirror having a plastic carrier base having advantages in optical characteristics, particularly, in reflection quality while avoiding problems relating to a heat treatment after coating. SOLUTION: The method includes steps of molding a carrier base from plastic having a curved base surface formed into a fixed shape prior to receiving a mirror coating, sputtering a first mirror coating layer of, for example, chromium onto the curved base surface, and sputtering a second mirror coating layer of aluminum onto the first layer. Further, an antiscratch coating may be applied on the second mirror coating layer to resist damages to the first and second mirror coating layers. COPYRIGHT: (C)2007,JPO&INPIT
