PROBLEM TO BE SOLVED: To provide a molten glass dropping nozzle capable of dropping a molten glass drop having a large mass, and a method and an apparatus for manufacturing a shaped glass capable of manufacturing a large-sized shaped glass using the molten glass dropping nozzle. SOLUTION: The molten glass dropping nozzle has a flow passage of molten glass inside and is for dropping the molten glass flowing from the opening of the flow passage installed at the tip as a molten glass drop, which has a plurality of the openings. Molten glass flown out from a plurality of the openings is formed at the tip integrally into a large-sized molten glass drop. COPYRIGHT: (C)2009,JPO&INPIT
