Abstract: Glass contains, in mol percentage on an oxide basis, SiO2: 35% to 60%, B2O3: 0.8% to 8%, Al2O3: 6% to 21%, and MgO: 17% to 44%. Additionally, (MgO/Al2O3)≥1 is satisfied, a measured Madelung constant m calculated by an expression (1A) is equal to or larger than 1.05, and a thermal expansion factor as a ratio of a measured value α of a linear thermal expansion coefficient to a calculated value αcal of a linear thermal expansion coefficient calculated from composition is equal to or smaller than 0.7. Herein, E is a measured value of a Young's modulus of the glass, Vp is an average atomic packing factor of the glass, and Gt is average bond dissociation energy of the glass.
