Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a nozzle for continuous graphite casting, capable of straightening molten metal, suppressing reduction in slab quality caused by adhesion or falling of nonmetallic inclusion to the inner hole surface of the continuous casting nozzle due to generation of a molten metal reservoir on an inner hole surface of the continuous casting nozzle, and also capable of preventing variations of a molten steel surface.SOLUTION: The nozzle 1 for continuous graphite casting includes a nozzle body 2 and a nozzle inner hole 3 provided inside the nozzle body 2. The inner hole surface 3a of the nozzle inner hole 3 is formed with a large number of dimples 5 where poured molten metal flows in and flows along the inner surface.
