Abstract:
The present invention relates to a chemically strengthened glass satisfying A1 [MPa] of 600 or more, A2 [MPa] of 50 or more, B1 [μm] of 6 or less, B2 [μm] of 10% or more of t [μm], C [MPa] of −30 or less, and A1/B1 [MPa/μm] of 100 or more when the chemically strengthened glass has a thickness t [μm] and a profile of a stress value [MPa] at a depth x [μm] from a glass surface is approximated by an error least-squares method in a region of 0 A2 and B1
