PROBLEM TO BE SOLVED: To provide a method for continuously casting a steel by which the occurrence of standing wave is effectively restrained, then, a cast slab having little non-metallic inclusion can stably be cast at high speed in a high through-put casting. SOLUTION: The method for continuously casting the steel is provided in which an immersion nozzle 2 having two spouting holes 12 at the lower part is used and molten steel 15 is poured into a mold so that molten steel flow 13 from the spouting holes is directed toward a short wall side of the mold 1, and thus a cast slab 19 is continuously cast, wherein the nozzle angleαof the immersion nozzle is set to be +10°to -40°, immersion depthηis set to be 50 to 350 mm and spouting hole diameters a x b to be 40 mm×40 mm to 100 mm×100 mm.
