A continuous casting method includes the steps of continuously supplying molten metal into a mold through at least one feed nozzle connected to the mold through a break ring, with the feed nozzle, the mold and the break ring forming at least a portion of a continuous casting apparatus, and intermittently withdrawing a cast piece formed from the molten metal in the mold thereby creating pressure in a space formed at a connecting point between the break ring, the mold and the cast piece as a result of the withdrawal from the mold. A shield means is placed to seal-off space between the at least one feed nozzle, and the mold to prevent entry of gas into the continuous casting apparatus and the pressure is reduced in the sealed-off space to thereby eliminate a pressure differential between the pressure in the sealed-off space and the pressure created in the space formed at the connecting point between the break ring, the mold and the cast piece during the intermittent withdrawal from the mold.
