A method for manufacturing a glass plate, includes processing for irradiating an inner circumferential edge surface extending along an inner hole in an annular glass plate with a laser beam along the inner circumferential edge surface. When the inner circumferential edge surface is irradiated with the laser beam, the laser beam is concentrated by a condenser lens and formed into diffused light, and the inner circumferential edge surface is irradiated with the diffused light from a direction inclined with respect to a main surface of the glass plate
