To provide a continuous casting machine which can attain both reduction of inclusions in a continuous casting product and flow control of a spout by a stopper.
The stopper 2 is formed to be a circular type in cross section, and a throughhole 11 which penetrates an axial core portion of the stopper 2 is provided along a flowing direction of molten metal in a trough 6, by which the molten metal passes through the throughhole 11 and flows. In a region at a downstream side of the stopper 2 of a diameter 2r, flow of a direction which is parallel to the flowing direction of the molten metal is forcedly generated along the flowing direction of the molten metal, by which generation of a harmful vortex is suppressed, and invasion of an oxide film on a molten metal surface is prevented.
