To provide a continuous casting mold with which even in the case of continuously casting molten metal for long time, a cast material having good surface characteristic can be produced at high productivity without causing any roughening and the rip on its surface.

The continuous casting mold 1 is formed into an inversely tapered shape widened toward the casting direction at 0.1-1.3° inclining angle on the inner surface thereof and composed of a material having ≥0.7 cal/cm.sec.°C thermal conductivity and ≥250 MPa yield stress. Further, the mold 1 is made of a material of copper alloy.
