Abstract: A linear groove is formed in a glass sheet along a programmed cut line that is set for the glass sheet, and pressure is applied locally to an end of the groove. The pressure is not applied equally uniformly to the whole groove but applied locally to the end of the groove, where an initial crack is induced by the pressure applied thereto.
