To provide a continuous casting device and a continuous casting method where the air caught by a spout is reduced, and further, the caught air is released from the spout at an early stage, thus inclusions in a continuously cast product can be reduced.

The shape at the inside of an inlet from a trough 6 in the spout neck 10a of a spout 10 is made into a continuous face 11, thus a smooth molten metal flow is made, and a steady rotary flow is not made present at the inside of the inlet of the spout. In this way, the air floated up inside the spout upon casting is straightly floated up along the vicinity of the center of the cross-section of the spout, i.e., along the wall face of a stopper rod, thus is eliminated from the upper part of the molten metal in the trough to the outside of the system.
