Abstract:
1. A glass article comprising: a glass sheet; and a photocatalyst film formed on a surface of the glass sheet, wherein the glass article has a reduced reflectance for light incident on the glass sheet due to the photocatalyst film, the photocatalyst film contains silicon oxide particles, titanium oxide particles, and a binder composed of silicon oxide component, the content of the silicon oxide particles falls in the range of 50 to 82 mass %, the content of the titanium oxide particles falls in the range of 8 to 40 mass %, and the content of the binder component falls in the range of 7 to 20 mass %, in the total amount of the silicon oxide particles, the titanium oxide particles, and the binder component, the silicon oxide particles have an average particle diameter that is at least 5 times an average particle diameter of the titanium oxide particles, some of the silicon oxide particles contained in the photocatalyst film serve as protruding silicon oxide particles, and some of the titanium oxide particles contained in the photocatalyst film are interposed between the glass sheet and the protruding silicon oxide particles,
