Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a continuous casting method for molten steel by which in the case of casting a slab, etc., by applying electromagnetic stirring to molten steel in a mold, defect such as scab and blister, caused by gas bubble and inclusion caught into the surface layer part of the cast slab, is prevented and the cast slab excellent in the quality characteristic is obtained in a good yield. SOLUTION: In the continuous casting method for the molten steel, in which the circular flow along the inner wall of the mold 14 is given by applying the electromagnetic stirring to the molten steel 11 in the mold 14, whirling flow is given from a meniscus 21 to the molten steel 11 at a position where thickness of the solidified shell is 20 mm.
