PROBLEM TO BE SOLVED: To provide a method for continuously casting a steel at high speed, capable of stably casting without generating constricted brake-out even in such high speed casting as to exceed 2.3 m/min casting speed. SOLUTION: In the method for continuously casting the steel while giving the vibration to a mold, when the steel is cast at a speed exceeding 2.3 m/min casting speed, the casting is performed under mold vibrating condition so that negative strip time, with which the mold descending speed is faster than the casting speed, becomes≥0.1 sec by adjusting the amplitude of casting vibration and the number of vibration.
