Abstract
The present invention provides a glass article including a photocatalyst film 1 containing silicon oxide particles 6 and titanium oxide particles 5, and a glass sheet 2. Assuming that the photocatalyst film 1 has a film thickness T, 80% or more of the titanium oxide particles are localized in a region between a surface of the glass sheet 2 and a position spaced from the surface by 0.6 T toward a surface of the photocatalyst film 1 in a thickness direction of the photocatalyst film 1. The glass article has an increased transmittance provided by enhancing the reflection-reducing function of the photocatalyst film 1 while maintaining the film strength and photocatalytic function of the photocatalyst film 1.
