Abstract
A chemically strengthened glass article in which a compressive stress value on a first surface is 400 MPa or more, a compressive stress value at a depth DB with a maximum compressive stress value in the range (0.05×t)−(0.15×t) μm is larger than the compressive stress value at a depth DA with a minimum compressive stress value in the range from the first surface to DB, a tensile stress value at a depth of (0.5×t) μm is 125 MPa or less, and a compressive stress layer depth is (0.23×t) μm or more.
