PROBLEM TO BE SOLVED: To provide a mold for continuous casting which, when electromagnetic force is applied and continuous casting is performed, produces a slab of high quality over a long period by preventing deterioration in the insulation of a mold. SOLUTION: The mold 21 causes electromagnetic force generated by an electromagnetic coil 16 installed in the outside of the mold 21 to act on a molten metal in the mold 21, thereby performing continuous casting. In the mold 21, for disturbing induced current circulating through the mold 21, a recessed groove 5 elongating to the casting direction is formed at the side face of a first cooling copper plate 1 arranged at the short-side side, i.e, at the butted face with a second cooling copper plate 2 arranged at the long-side side, a first electrical insulating material 6 is provided at the part in which the recessed groove 5 is not formed, and further, the inside of the recessed groove 5 is provided with a second electrical insulating material 7 projecting from the surface of the first electrical insulating material 6.
