Abstract: A continuous casting method of steel of continuously casting a slab by using a vertical liquid bending type continuous casting machine. The method includes, while performing continuous casting by using an in-mold electromagnetic stirring device, applying an alternating-current moving magnetic field that moves in a width direction of a mold to molten steel inside the mold, inducing a swirling flow in the molten steel, and stirring the molten steel. A travel speed of the alternating-current moving magnetic field calculated by a specified formula is in a range of 0.20 to 1.50 m/s.
