Abstract: The present invention relates to a chemically strengthened glass, satisfying: a ratio ICS (≥400)/ICS being more than 0.13 in a stress profile, the ICS representing an integrated value of compressive stress in a region from a surface of the glass to a depth where the compressive stress becomes 0 in the stress profile, and the ICS (≥400) representing an integrated value of compressive stress in a region from a depth of 400 μm from the surface of the glass to the depth where the compressive stress becomes 0 in the stress profile.
