Disclosed is a glass with low solar transmittance, which is characterized by that it has a basic composition of soda-lime-silica glass, that it contains as coloring components 0.70-1.70 mass % of Fe 2 O 3 (total iron in terms of ferric iron), 0.15-0.45 mass % of FeO (ferrous iron), 0-0.8 mass % of TiO 2 , 100-350 ppm of CoO, 0-60 ppm of Se, 100-700 ppm of Cr 2 O 3 , and 3-150 ppm of MnO, that it has a ratio (Fe 2+ /Fe 3+ ) of ferrous iron to ferric iron of 0.20-0.80. This glass has superior ultraviolet absorbing performance and infrared absorbing performance (heat insulation performance) and an appropriate transparency.
