A plate glass (G1) cut by laser fusion-cutting, configured so as to have a ratio of 0.01 between the area of width regions (E) and the area in which dross (D) of a particle diameter of at least 2 µm is attached in each width region (E), said regions (E) being on the surface side and rear surface side and having a width of 400 µm from the boundary between an end surface formed by cutting and the front/rear surfaces. |
