Abstract

The present invention provides a glass article which is provided with a photocatalyst film (1) that contains silicon oxide particles (6) and titanium oxide particles (5) and which has improved reflection suppressing function and further increased transmittance while maintaining the film strength and photocatalytic function of the photocatalyst film (1). The photocatalyst film (1) contains 72 79% by mass of the silicon oxide particles 13 18% by mass of the titanium oxide particles and 8 14% by mass of a binder component that is mainly composed of silicon oxide respectively relative to the total mass of the silicon oxide particles (6) the titanium oxide particles (5) and the binder component. The silicon oxide particles have an average particle diameter of 30 200 nm; the titanium oxide particles have an average particle diameter of 5 20 nm; and the average particle diameter of the silicon oxide particles is not less than 5 times the average particle diameter of the titanium oxide particles. If T is the film thickness of the photocatalyst film 80% or more of the titanium oxide particles are concentrated in a region within 0.6T from the surface of a glass plate (2).
