NOVELTY - The glass article consists of photocatalyst film (1) formed on the surface of a glass plate (2). The photocatalyst film contains 50-82 %mass of silicon oxide particles (6,7), 8-40 %mass of titanium oxide particles (5) and 7-20 %mass of binder component comprising silicon oxide with respect to total amount of silicon oxide particles, titanium oxide particles and binder component. A portion of the silicon oxide particles is protruded silicon oxide particles. A portion of titanium oxide particles is interposed between the protruded particles and glass plate.    USE - Glass article e.g. cover glass for solar cell and glass for greenhouse.    ADVANTAGE - The glass article has improved lifetime. The photocatalyst film has high strength, improved photocatalytic function and reflection suppression function.    DETAILED DESCRIPTION - The glass article consists of photocatalyst film formed on the surface of a glass plate. The photocatalyst film contains 50-82 %mass of silicon oxide particles, 8-40 %mass of titanium oxide particles and 7-20 %mass of binder component comprising silicon oxide with respect to total amount of silicon oxide particles, titanium oxide particles and binder component. The average particle diameter of the silicon oxide particles is 5 times or more the average particle diameter of titanium oxide particles. A portion of the silicon oxide particles is protruded silicon oxide particles. A portion of titanium oxide particles is interposed between the protruded particles and glass plate. The protruded particles are not in contact with the glass plate and are at a distance on the glass plate rather than the top portion of the titanium oxide particles contacting the silicon oxide particles. The top portion of the protruded particles is exposed to the surface of the photocatalyst film.    DESCRIPTION OF DRAWING(S) - The drawing shows the sectional view of the glass articles.
