Abstract
A ultraviolet ray absorbent glass comprises a substrate glass, a ultraviolet ray absorbent film including as the major component at least one selected from the group consisting of zinc oxide, titanium oxide and cerium oxide, and an intermediate film having an intermediate refractive index which is between the refractive indices of the ultraviolet absorbent film and the substrate glass, the intermediate film being located between the ultraviolet absorbent film and the substrate glass, whereby iridescence by the ultraviolet ray absorbent film is reduced, and a heat reflecting function is imparted.
