Abstract
Provided is a glass article that improves the film strength of a photocatalyst film while maintaining the photocatalytic function and the reflection suppressing function of the photocatalyst film. The photocatalyst film on the glass sheet is formed to contain, in mass %, 50 to 82% of silicon oxide particles, 8 to 40% of titanium oxide particles, and 7 to 20% of a binder component composed of silicon oxide. The average particle diameter of the silicon oxide particles is set to at least 5 times the average particle diameter of the titanium oxide particles. The photocatalyst film is formed to have a structure such that some of the silicon oxide particles in the film serve as protruding silicon oxide particles that are not in contact with the glass sheet and that have their top portions protruding from the surrounding titanium oxide particles and being exposed on the surface of the film, while some of the titanium oxide particles are interposed between the glass sheet and the protruding silicon oxide particles.
