Abstract
The present invention is a bushing for manufacturing a glass fiber that includes a base plate, a plurality of nozzles for discharging molten glass, and a nozzle group in which the plurality of nozzles are arranged in lines, being bonded to the base plate, wherein nozzles constituting at least one nozzle array among nozzle arrays of outermost layers of the nozzle group are plugged to a half or more of a nozzle length from a tip in depth. The glass-fiber-production bushing plate makes long-term, stable discharge of a uniform glass flow possible.
