A nozzle put into a molten metal in vertical upwards continuous casting for casting a cast product by pulling up the molten metal, the nozzle comprising:
- an upper cap;
- a nozzle body having an intake hole through which the molten metal is taken in;
- and
- a flange portion formed on a lower side of the nozzle body, with the nozzle body, which has an extending direction, comprising a hollow cylindrical passage having constant inner and outer diameters that extend from the upper cap to a lowermost opening in the hollow cylindrical passage that is fluidly closed by the flange portion, which projects outwardly beyond the outer diameter of the hollow cylindrical passage of the nozzle body, such that the intake hole is formed in a lateral surface of the hollow cylindrical passage at a distance above the lowermost opening in the hollow cylindrical passage and extends to the outer diameter of the hollow cylindrical passage in a direction perpendicular to the extending direction of the nozzle body.
