Abstract
The present invention relates to a chemically strengthened glass having a sheet shape, having a compressive stress layer on a glass surface, having a compressive stress value on the glass surface of 800 MPa or more, having a sheet thickness (t) of 100 μm or more, having a depth of the compressive stress layer (DOL) of (t×0.1) μm or more, and satisfying: CS>CS>0, where Dis a depth in a range of 10 μm or more and not more than DOL from the glass surface, at which a compressive stress value is maximum; CSis the compressive stress value at the depth D; Dis a depth in a range of equal to or less than Dfrom the glass surface, at which a compressive stress value is minimum; and CSis the compressive stress value at the depth D.
