Original Abstract Submitted
A glass includes, as represented by mol % of element: 12% to 16% of P; 16% to 21% of Sn; 50% to 60% of O; 5% to 15% of F; 0% to 3% of Zn; 0% to 1% of Si; 0% to 1% of B; and 0% to 3% of Al, and (Sn+Zn)/P is 1.25 to 1.55. A glass transition temperature Tg is 80° C. to 200° C. When an absorbance per 1 mm thickness at a wave number of 3100 cmis defined as A3100 and an absorbance per 1 mm thickness at a wave number of 3240 cmis defined as A3240 in an infrared absorption spectrum, A3240/A3100 is 0.6 to 1.2.
