摘要
The present invention provides a glass substrate of an electronic device cover glass with improved strength of the end face having an apex. glass substrate of the present invention has an end face adjacent the pair of main surfaces, end surfaces has a shape having a top portion when viewed in cross section, has a compressive stress layer by chemical strengthening, the maximum compressive stress value 600MPa or more and a depth of compression stress layer is 60 m or less. Apex angle of the apex [degrees], the maximum compressive stress value CS of surface [MPa], the depth of the compressive stress layer d [ m] is, 600MPa -3.5 (d / sin ( / 2)) satisfy the relationship of -d + CS.
