PROBLEM TO BE SOLVED: To provide a nozzle for continuous casting which is effective in preventing the clogging of the nozzle and capable of integral forming during a forming operation. SOLUTION: In a nozzle 10 for continuous casting capable of preventing the clogging of the nozzle caused by stuck alumina in continuous casting of steel, an in-nozzle hole part 11 in contact with the molten steel is made of a refractory material containing 1-10wt.% carbon, and refractory materials other than carbon are of grain size of <=420μm. The refractory material forming the in-nozzle hole part 11 is of the integrated structure which is simultaneously formed in forming the nozzle for continuous casting, and the thickness of the part is in the range of 2-12mm.
