[PROBLEMS] A green UV-infrared-absorbing glass having no environmental problems does not satisfy the user-specified color tone and physical properties. In A weight percentages, the total Fe 2 O 3 0.3~0.5%, CeO 2 0.8~2.0%, TiO 2 0.8~2.0%, FeO 0.10~ Soda lime glass containing at least 0.25% coloring component, the glass is 5 mm thick, UV transmittance is 9% or less, 350 nm wavelength transmittance is 1% or less, 550 nm wavelength transmittance is 70% or more, 1100 nm wavelength Ultraviolet ray infrared absorbing green glass having a transmittance of 25% or less. FeO / Fe 2 O 3 by weight ratio is 0.3 to 0.6, CeO 2 / TiO 2 is 0.7 to 1.3, visible light transmittance is 67% or more, solar radiation transmittance is 48% or less, dominant wavelength by illuminant D 65 is 510 to 560 nm, excitation purity Yusuke also feature more than 10%.
