A method for bending a glass plate for a laminated glass comprises a step of heating at least two glass plates separately at a temperature suitable to conduct bending operation and bending them; a step of gradually cooling each of them; a step of transferring the at least two glass plates onto a bending ring mold in an overlapping state; and a step of heat-shaping the overlapping glass plates on the bending ring mold so that the surfaces of the glass plates are fitted to and are in coincidence with each other.
