Provided are near-infrared light-absorbing glass in which good color
compensating characteristics are maintained even without containing
harmful arsenic, permitting the thinning of the glass, and having good
weatherability and forming properties; a near-infrared light-absorbing
element comprised of such glass; a near-infrared light-absorbing filter
employing such glass. Also provided, at low cost, are near-infrared
light-absorbing glass permitting good color compensating, a near-infrared
light-absorbing element comprised of such glass, and a near-infrared
light-absorbing filter comprising such elements. The glass comprises
cationic components with a certain composition as well as F.sup.- and
O.sup.2- as anionic components. Alternatively, the glass is near-infrared
light-absorbing glass, wherein the glass exhibits properties, based on a
thickness of 0.5 mm, in the spectral transmittance of wavelengths of 400
to 700 nm, that wavelength, at which a 50 percent transmittance is
exhibited, is less than 630 nm, transmittance at a wavelength longer than
said wavelength is less than 50 percent, transmittance at a wavelength
shorter than said wavelength is higher than 50 percent and the viscosity
at a liquid phase temperature is 0.5 Pas or more. The near-infrared
light-absorbing element is comprised of such glass. The near-infrared
light-absorbing filter comprises a glass plate comprised of such glass.
Alternatively, the glass is comprised of fluorophosphate glass or
phosphate glass, and comprises 0.1 weight percent or more of copper based
on CuO, 0.005 to 0.5 weight percent of iron based on Fe.sub.2O.sub.3,
0.01 to 1 weight percent of antimony based on Sb.sub.2O.sub.3, and no
arsenic.
