Abstract:
To provide cover glass for mobile terminals exhibiting high strength in a thin plate thickness state to enable reductions in thickness of apparatuses when inserted in the apparatuses, cover glass (1) for a mobile terminal of the invention is cover glass (1) that is obtained by forming a resist pattern on main surfaces of a plate-shaped glass substrate, then etching the glass substrate with an etchant using the resist pattern as a mask, and thereby cutting the glass substrate into a desired shape and that protects a display screen of the mobile terminal, where an edge face of the cover glass (1) is formed of a molten glass surface, and as surface roughness of the edge face, arithmetic mean roughness Ra is 10 nm or less.
