Abstract

A full body of a glass sheet (G) is cut by forming an initial crack () on a preset cutting line () of the glass sheet (G) that is supported by a support member (()) from a back surface side of the glass sheet (G), followed by propagating the initial crack () while passing through the glass sheet from a front surface to the back surface thereof due to a stress generated through localized heating along the preset cutting line () and cooling of a heated region that is formed through the localized heating, the glass sheet (G) being supported by the support member (()) from the back surface side through an intermediation of an elastic sheet (E) having low thermal conductivity.
