Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an immersion nozzle for continuous casting, capable of relieving inflow speed of molten steel and averaging an amount discharged from right and left discharge ports and lessening variations of a molten steel surface caused by wave motions.SOLUTION: The immersion nozzle 1 for continuous casting includes a nozzle body 2, a nozzle internal hole 3 arranged inside the nozzle body 2 and circulating the molten steel, and a pair of discharge ports 4a, 4b arranged so as to be opposite to a lower part of the nozzle body 2. The nozzle internal hole 3 is arranged so as to be opposite to an upper part of the pair of discharge ports 4a, 4b, and has a pair of level differences 5a, 5b continued over the top and bottom of a meniscus A.
