Abstract: The invention relates to a glass including, as represented by mol % based on elements: 8-25% of P; 8-40% of Sn; 20-80% of O; and 1-50% of F, in which the glass has a glass transition temperature Tg of 300° C. or lower, and the glass gives an infrared absorption spectrum satisfying A3240/A3100 of 0.6-1.2, where the A3100 is an absorbance per 1-mm thickness at a wavenumber of 3,100 cm−1 and the A3240 is an absorbance per 1-mm thickness at a wavenumber of 3,240 cm−1.
