| 摘要 |
The present invention provides a variable reflectance mirror, comprising a color layer that develops color by binding to hydrogen or lithium, a transparent substrate formed on or above one surface of the color layer, a light-reflecting layer which allows transmission of hydrogen or lithium provided on the side of the color layer opposite to the surface thereof on which the transparent substrate is formed, and a supplying device for supplying hydrogen or lithium to the color layer, wherein a transparent intermediate layer which allows transmission of hydrogen or lithium and having a refractive index smaller than that of the color layer is formed between the color layer and the light-reflecting layer.
