PROBLEM TO BE SOLVED: To provide a method for drawing a continuously cast slab after the completion of casting where, after the completion of the injection of a molten steel into a mold, when the slab in a continuous casting machine is drawn out to the lower part of the mold, the leakage of the topmost slab in the secondary cooling zone in which the topmost slab is made close to a horizontal state from the final part of the casting is prevented. SOLUTION: When, after the completion of the injection of a molten steel 11 into a mold 5, while supporting a slab 12 by a plurality of driving rolls 8 and a plurality of guide rolls 7, it is drawn out from a continuous casting machine; before the final part of the casting in the topmost slab tip reaches the installment position of the driving roll, the driving rolls at least installed in a straightening zone 16 is released the pressure which has been applied to the slab for grasping the slab. In this case, it is preferable that, before the distance between the final part of the casting and the respective driving rolls reaches to <4 m, the pressure is released.
