Abstract
The present invention relates to a chemically strengthened glass satisfying A[MPa] of 600 or more, A[MPa] of 50 or more, B[μm] of 6 or less, B[μm] of 10% or more of t [μm], C [MPa] of −30 or less, and A/B[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×[μm] from a glass surface is approximated by an error least-squares method in a region of 0<x<3t/8 using the following function while defining a compressive stress as positive and a tensile stress as negative: Aerfc(x/B)+Aerfc(x/B)+C, in which erfc is a complementary error function, and relations of A>Aand B<Bare satisfied.
