Abstract: A chemically strengthened glass has a compressive stress layer formed in a glass surface layer by ion exchange. The compressive stress layer includes at least two types of stress patterns of a stress pattern A close to a glass surface and a stress pattern B on an inner side of the glass. In the stress pattern A, compressive stress increases as going inward from the glass surface. In the stress pattern B, compressive stress decreases as going inward from the glass surface. Depth of compressive stress layer in the stress pattern B is 90 μm or more from the glass surface. Compressive stress α MPa of the glass surface in the stress pattern A and compressive stress β MPa at a point where the stress pattern A and the stress pattern B cross each other satisfy a relation of β>α.
