Abstract: A soda lime glass plate has, on the basis of oxides, a total sulfur content in terms of SO3 of 0.001 to 0.2% in mass %, a total iron content in terms of Fe2O3 of 0.15 to 0.4% in mass %, and a total tin content in terms of SnO2 of 0.02 to 1% in mass %, and has a mass proportion of a divalent iron in terms of Fe2O3 in the total iron in terms of Fe2O3 of 45 to 70%. The soda lime glass plate has, as a conversion value for a 3.85 mm-thickness glass plate, a visible light transmittance Tv_A of 70% or more, a total solar transmittance Tts of 63.7% or less, and c* in the L*a*b* color space of 4 or less.
