英文摘要	Provided is an optical element manufacturing method by which optical elements, such as a beam shaping element having a molded side surface, are highly efficiently and accurately manufactured by pressure-molding a molten glass drop. After supplying a lower molding die with the molten glass drop of a prescribed volume at a temperature higher than that of the molding die, the molten glass drop is pressure-molded by the molding die, and a free surface solidified without being in contact with the molding die is formed between a molded upper surface and the molded side surface. The volume of the molten glass drop to be supplied is 0.8 times or more but not more than 0.97 times the volume of a space configured by an extended molded upper surface, an extended molded side surface and the molded lower surface when the molded upper surface and the molded side surface are extended.
