1. A glass plate working method comprising the steps of:
forming on one surface of a glass plate a scribe groove constituted by a closed curve with a cutter wheel, the scribe groove being directed in a thickness direction of the glass plate in such a manner as to be inclined toward an inner region of the closed curve; and lifting an inner region of the glass plate inside the closed curve from another surface of the glass plate in a state in which an outer region of the glass plate outside the closed curve is pressed from one surface of the glass plate with the scribe groove formed thereon, to bend the glass plate in a convex shape toward a side of the one surface so as to cause the scribe groove to proceed toward the other surface facing to the one surface of the glass plate, and removing the inner region of the glass plate inside the closed curve from the outer region of the glass plate outside the closed curve.
