Abstract

The coated glass sheet of the present invention includes: a glass sheet; and a coating film provided on at least one principal surface of the glass sheet and having a smooth surface. The coating film includes: isolated closed pores present within the coating film; and a matrix. The coating film is substantially free of open pores open at the surface of the coating film. For the coated glass sheet of the present invention, a transmittance gain is 2.5% or more, the transmittance gain being calculated by subtracting an average transmittance of the glass sheet as determined by applying light having wavelengths of 380 to 1100 nm to the glass sheet in the absence of the coating film on the surface of the glass sheet from an average transmittance of the coated glass sheet as determined by applying light having the wavelengths to the coated glass sheet from a side on which the coating film lies.
