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.

Abstract: A method for producing a glass substrate includes (a) a step of forming molten glass having a temperature T2 less than or equal to 1500° C. on molten tin having an iron concentration greater than or equal to 100 ppm to produce a glass ribbon having a temperature T4 less than or equal to 1100° C. and a logarithm log ρ greater than or equal to 8.8, and (b) a step of cooling the glass ribbon to room temperature to produce the glass substrate. The temperature T2 represents a temperature when a logarithm of a viscosity η (dPa·s) is 2, the temperature T4 represents a temperature when the logarithm of the viscosity η (dPa·s) is 4, and the logarithm log ρ represents a logarithm of a volume resistivity ρ (Ω·cm) at 150° C.
