An apparatus for supplying molten steel and a continuous casting method therewith are described. The apparatus is equipped with a tundish having an upper nozzle at the bottom, a flow control mechanism disposed below the upper nozzle an immersion nozzle formed by a refractory material having a good electrical conductivity, one electrode disposed in the inner space of the tundish the other electrode disposed in the immersion nozzle and a power supply connected to the electrodes and In the method, the molten steel is supplied into a mold in the state of supplying an electric current between the inner surface of the immersion nozzle and the molten steel passing through the inside thereof by utilizing the apparatus for supplying molten steel. The deposition of the Al oxide or the like in the molten steel onto the inner surface of the immersion nozzle and others can be prevented, and thereby the generation of the surface defects in the products can also be prevented.
