An ultraviolet/infrared absorbent glass plate includes base glass including 65 to 80 wt. % SiO2; 0 to 5 wt. % Al2O3; 0 to 10 wt. % MgO; 5 to 15 wt. % CaO; 10 to 18 wt. % Na2O; 0 to 5 wt. % K2O; 5 to 15 wt. % a total amount of MgO and CaO; 10 to 20 wt. % a total amount of Na2O and K2O; 0.05 to 0.3 wt. % SO3; 0 to 5 wt. % B2O3; 0 to 1 wt. % SnO2; and 0 to 350 ppm MnO; and colorants including 0.2 to 0.45 wt. % total iron oxide (T-Fe2O3) expressed as Fe2O3; 0.01 to 0.03 wt. % (excluding 0.03 wt. %) FeO; 0.8 to 2 wt. % CeO2; 0 to 0.003 wt. % CoO; and 0 to 1.5 wt. % TiO2. FeO expressed as Fe2O3 is 5 to 10 wt. % (excluding 10 wt. %) of T-Fe2O3, and the glass at any thickness in a range of 3.25 mm to 6.25 mm has visible light transmittance of equal to or more than 80% when measured by using CIE illuminant A.
