PROBLEM TO BE SOLVED: To obtain glass having a coating film, which has decreased reflectance to radiowaves in each frequency band of TV broadcast, satellite broadcast and mobile phone, sufficient shielding performance to solar insolation and transmissivity to visible rays. SOLUTION: A mixed dispersion layer obtained by mixing a metal nitride and Ag is formed on the surface of a transparent substrate, and then an Ag-containing layer at least containing Ag, such as an Ag-mixed layer obtained by mixing a metal nitride and Ag, is formed on the mixed dispersion layer. Thereafter, an Ag particulate layer comprising particulate Ag is formed on the surface layer of the film by heating the formed films at a temperature of≥150°C and not higher than the softening temperature of the transparent substrate.
