| 摘要 |
A high-reflectivity surface reflecting mirror is provided by sequentially forming, on a resin substrate, a silicon dioxide first under layer, a chromium sulfide second under layer, a silver reflecting layer and protective layers. According to a second aspect of the invention, a surface reflecting mirror is provided by sequentially forming, on a resin substrate, a silicon dioxide under layer, an aluminum reflecting layer, a silicon dioxide first protective layer, a second protective layer made of at least one of titanium oxide, tantalum oxide and zirconiumoxide, and an aluminum oxide third protective layer.
