A laser fusion-cutting method for plate glass, that irradiates a laser (L) from a surface (S) side, along a planned cutting line (X) extending in the surface direction of plate glass (G), and cuts the plate glass (G). The method uses a configuration whereby a shaping gas (A3), sprayed so as to form a flow along the surface of at least either the front or rear surface (S, B) of the plate glass (G), passes through an irradiation section (C) for the laser (L). |
