To provide a continuous casting method which suppresses an increase in a nitrogen content and reduces surface defects in casting a metal piece.
A continuous casting device 100 for casting a stainless steel piece 3c includes a long nozzle 2 extending in a tundish 101 and arranged on a ladle 1 in order to inject stainless molten steel 3 in the ladle 1 into the tundish 101. Furthermore, nitrogen gas 4 as seal gas is supplied in a periphery of the stainless molten steel 3 in the tundish 101. As an injection port 2a of the long nozzle 2 is immersed in the stainless molten steel 3 in the tundish 101, the stainless molten steel 3 is injected in the tundish 101 through the long nozzle 2, and the stainless molten steel 3 in the tundish 101 is injected in a mold 105 to continuously cast the stainless steel piece 3c.
