視光反射率が５０％と高い。[Problems to be Solved by the Invention] A glass plate having a gold reflection color to which a titanium nitride film is adhered or a copper-aluminum alloy film and a titanium oxide film are adhered is a titanium nitride film, or a copper or copper-aluminum alloy. Although the unique color of the film is used, the visible light reflectance on the film surface side is high in all cases, and the visible light reflectance of 10% or less cannot be achieved. And copper, or copper-
A glass plate having an aluminum alloy film and a titanium oxide film adhered to it and having a gold reflection color is not practical unless it is used as a double-glazing glass because the film easily corrodes. Further, a glass plate having a golden reflection color using a tin oxide film and a chromium nitride film adjusts the reflection color on the glass plate surface side by utilizing the optical interference effect of the multilayer film. The visible light reflectance on the side is as high as 50%.
