PROBLEM TO BE SOLVED: To provide a molten glass dropping nozzle which can drop a molten glass drop having a large mass and has less nonuniformity of dropping position, and a method and an apparatus for manufacturing a shaped glass capable of stably 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 and a projection at the center of the tip. Molten glass flown from a plurality of the openings of the nozzle is formed integrally into a molten glass drop at the tip and supplied in dropping into a lower mold. The supplied molten glass is press-molded in molds, to manufacture a shaped glass. COPYRIGHT: (C)2009,JPO&INPIT
