Abstract: A glass substrate comprising a rectangular glass sheet having a first main surface and a second main surface opposite the first main surface, the glass substrate having a first side and a second side which are adjacent to each other in a view along a thickness direction of the glass sheet, in which a thickness tolerance is less than 6.26 μm in a first cross section which is a cross section in the thickness direction of the glass sheet along a straight line parallel to the first side, the thickness tolerance being a difference between the maximum value and the minimum value of the thickness of the glass sheet.

Abstract: The present invention relates a non-alkali glass, having a Young's modulus (E) of from 70 GPa to 95 GPa and an average coefficient of thermal expansion a from 50° C. to 350° C. of from 32 to 45 (×10−7/° C.), and which satisfies the following formula (1): 20α+7E≥1310. The non-alkali glass has a composition in terms of mol % on the basis of oxides, satisfying the relationship of: 759−13.1×SiO2−7.5×Al2O3−15.5×B2O3+9.7×MgO+21.8×CaO+27.2×SrO+27.9×BaO≥0.
