To provide a device and a method for feeding molten glass where temperature falling at the edge of an outflow pipe is suppressed and to provide an apparatus and a method for producing a glass molded body.

The device 10 for feeding the molten glass is equipped with the outflow pipe 20 to flow the molten glass out and a heating part 30 to heat the edge 23 of the outflow pipe 20. The edge 23 is covered with a cover 40 placed outside with a gap. The heating part 30 has coils 31 wound at the outer periphery of the cover 40 and a high frequency power source 33 to supply a high frequency current to the coils 31 and the edge 23 is induction-heated.
