PROBLEM TO BE SOLVED: To provide a continuous casting method by which the quality of a cast slab can be improved while holding high lubrication in a mold by controlling the flowing amount of powder to a suitable amount even in the case of changing a casting condition. SOLUTION: In the continuous casting method, by which the casting is performed by using the mold 1 whose inner surface shape near at least molten steel surface is formed as a reverse tapered shape widened toward the lower part in the drawing-out direction of the cast slab, and by adding the mold powder 6 on the molten steel surface 12 in the mold 1, an effective reverse tapered length in the reverse tapered mold is adjusted by adjusting the molten steel surface position so as to control the flowing amount of the mold powder.
