PROBLEM TO BE SOLVED: To provide a method for continuously casting molten steel with which even in the case of casting at high speed than the present casting, the quality of a slab is not lowered, and bulging exceeding a allowable value in short side is not developed. SOLUTION: When the molten steel is supplied into a mold in a continuous caster through a straight immersion nozzle having a linear through-hole from a tundish holding the molten steel, static magnetic field generators are disposed at the lower ends of the long sides of the mold and also, the static magnetic field impressive intensity (gauss) is made into the following range to supply the molten steel. The static magnetic field impressive intensity (gauss) >= the molten steel spouting quantity (ton/min-strand)×100 from the straight immersion nozzle.
