Abstract
A heat-absorbing glass plate containing iron, tin, selenium, cobalt and sulfur, where the mass ratio of divalent iron as calculated as FeOto total iron as calculated as FeOis at least 55%, the ratio Tv/Te of the visible light transmittance Tv (by illuminant A, 2° visual field) as defined in JIS R3106 (1998) calculated as 4 mm thickness of the glass plate to the solar transmittance Te as defined in JIS R3106 (1998) calculated as 4 mm thickness of the glass plate, is at least 1.5, the visible light transmittance Tv (by illuminant A, 2° visual field) is higher than 65% as defined in JIS R3106 (1998) calculated as 4 mm thickness of the glass plate, and the excitation purity Pe is at most 7% as defined in JIS Z8701 (1999) calculated as 4 mm thickness of the glass plate.
