Abstract
A glass plate includes a first surface provided with a first film; and a second surface provided with a second film and opposite to the first surface. Each of the first film and the second film includes mainly tin oxide and has a sheet resistance value of 20 Ω/□ or less. When film thicknesses of the first and second films are θ1 nm and θ2 nm respectively, and when, in the glass plate, a haze value measured from the first surface side for a configuration provided with the first film only is H1 (%), and a haze value measured from the second surface side for a configuration provided with the second film only is H2 (%), a value of θ1 divided by H1 is 500 or more but 1200 or less, and a value of θ2 divided by H2 is 300 or more but 750 or less.
