PROBLEM TO BE SOLVED: To provide: a method for manufacturing glass moldings, by which direct hit of gas ejected from each receiving mold (gob mold) on a flow-out port can be prevented; a method for manufacturing optical elements by molding the glass moldings obtained the method; and the like. SOLUTION: The method for manufacturing the glass moldings comprises allowing molten glass flowing out from a flow-out port to fall, receiving the molten glass with a plurality of receiving molds each ejecting gas, and forming the molten glass on each receiving mold while ejecting gas. In this method, each receiving mold is moved so that the receiving mold comes immediately below the flow-out port immediately before the molten glass is allowed to fall, then the mold receives the fallen molten glass, and the molten glass is molded.
