Abstract
The present invention relates to a chemically strengthened glass sheet in which a value of SB/(SA×t) is 5.0 mm−1 or more, where SA (MPa·μm) is an integrated value of a compressive stress from a surface of the glass sheet to a depth of 10 μm, SB (MPa·μm) is an integrated value of a compressive stress from the depth of 10 μm to DOL which is a depth at which the compressive stress is zero, and t (mm) is a thickness of the glass sheet.
