Abstract:
A chemically strengthened glass having a thickness t of 2 mm or less, having a compressive stress value (CS90) at a portion of 90 μm deep from a glass surface being 25 MPa or more, and satisfying a number of fragments generated within a size of 25 mm×25 mm being 20 or less in a fracture test according to an indenter indentation test under a condition of holding a load ranging from 5 kgf to 10 kgf for 15 seconds with a pyramidal diamond indenter having an indenter angle of a facing angle of 60°.
