To provide a method for supplying a molten glass, capable of reducing the irregularity of the supply amounts on the supply of the molten glass to a mold and thus capable of improving the qualities of the molded lenses, and to provide a device for supplying the same.

A high frequency coil 3 for heating a molten glass 2 is wound on the outer periphery of a crucible 1. A nozzle 4 is disposed in the lower part of the crucible 1. The nozzle 4 is formed in a two stage shape where the upper part 4a is thicker than the lower part 4b. A plunger 5 is vertically movably supported in the crucible 1 with a lifting mechanism 8. A flat plate-like stopper 6 for stopping the supply of a molten glass 2 is attached to the tip of the plunger 5. A flat plate-like stopper 7 is attached above the stopper 6.
