摘要： The present invention provides a glass member including a photocatalyst layer and a heat reflecting layer, the glass member having high photocatalytic activity and exhibiting a low reflectance and a colorless or pale blue reflection color tone or a bluish green or green reflection color tone. The glass member is produced by laminating an antistripping layer made of silicon oxide or the like, a crystalline undercoat layer made of zirconium oxide or the like and a photocatalyst layer made of titanium oxide or the like on the other surface of a glass substrate having a heat reflecting layer formed on one surface thereof. The heat reflecting layer is formed such that the other surface of the glass substrate has a reflection chromaticity (a*, b*) satisfying -4≤a*≤2 and -5≤b*≤0 and a visible light reflectance of 10% or less, the crystalline undercoat layer is allowed to have a thickness ranging from 2 to 28 nm, and the photocatalyst layer is allowed to have a thickness ranging from 2 to 20 nm, whereby the glass member having a colorless or pale blue reflection color tone can be produced. Likewise, the heat reflecting layer is formed such that the reflection chromaticity (a*, b*) satisfies -15≤a*≤-2 and -10≤b*≤10 and the visible light reflectance is 13% or less, the crystalline undercoat layer is allowed to have a thickness ranging from 2 to 28 nm, and the photocatalyst layer is allowed to have a thickness ranging from 2 to 14 nm, whereby the glass member having a bluish green or green reflection color tone can be produced.
