Glass sheet

A glass sheet comprising a first main surface and a second main surface opposite to the first main surface in a thickness direction, wherein

• X represented by the following formula (1) is −0.29<X<0.29;
• and
• F0-3 determined according to the following formula (II) is 0.02 or more:
• A×Δ1H/30Si+B×ΔNa2O+C×ΔSn+D×ΔF=X (1)
• wherein in the formula (1), each parameter has the following meaning:
• A1H/30Si:
• a value of difference obtained by subtracting an average count by secondary ion mass spectroscopy (SIMS) at a depth of 3 to 12 μm in the second main surface from an average 1H/30Si count by SIMS at a depth of 3 to 12 μm in the first main surface;
• ΔNa2O:
• a value of difference obtained by subtracting an average Na2O concentration (wt %) by XRF at a depth of 0 to 3 μm in the second main surface from an average Na2O concentration (wt %) by XRF at a depth of 0 to 3 μm in the first main surface;
• ΔSn:
• a value of difference obtained by subtracting Tin count as an indicator of tin content in a glass by XRF at a depth of 0 to 10 μm in the second main surface from the value of Tin count as an indicator of tin content in a glass by XRF at a depth of 0 to 10 μm in the first main surface;
• ΔF:
• a value of difference obtained by subtracting an average fluorine concentration (wt %) by SIMS×12 at a depth of 0 to 12 μm in the second main surface from an average fluorine concentration (wt %) by SIMS×12 at a depth of 0 to 12 μm in the first main surface;
• A:
• −128.95;
• B:
• 1;
• C:
• −0.0002428;
• and
• D:
• −0.009922:
• and
• F0-3=[average fluorine concentration by SIMS at depth of 0 to 3 μm in first main surface]×3 (II).
