A continuous casting mold having a mold copper plate composed of copper or a copper alloy, the mold comprising: plural separate portions filled with a foreign metal of which thermal conductivity is 80% or less of thermal conductivity of the mold copper plate or 125% or more thereof, the plural separate portions being formed as circular concave grooves having a diameter of 2 mm to 20 mm or as quasi-circular concave grooves having a circle-equivalent diameter of 2 mm to 20 mm, the grooves being provided on an inner wall surface of the mold copper plate, the plural separate portions being provided on an inner wall surface of the mold copper plate so that thermal resistance of the mold increases and decreases regularly and periodically in a width direction and a casting direction of the mold in vicinity of a meniscus, and the plural separate portions being formed at least in a region from the meniscus to a position located 20 mm or more lower than the meniscus, the region being whole or part of the inner wall surface, wherein, a ratio of Vickers hardness HVc [kgf/mm 2 ] of the mold copper plate to Vickers hardness HVm [kgf/mm 2 ] of filled foreign metal satisfies relational expression below: 0.3 ≤ HVc / HVm ≤ 2.3 and the ratio of the thermal expansion coefficient αc [μm/(m×K)] of the mold copper plate to the thermal expansion coefficient αm [μm/(m×K)] of the filled foreign metal satisfies relational expression below: 0.7 ≤ α c / α m ≤ 3.5 and wherein a coating layer is formed on the inner wall surface by a plating method or a thermal spraying method, the coating layer having a breaking elongation of 8% or more determined in accordance with "Metallic materials-Tensile testing" prescribed in JIS Z 2241, and the portions filled with the foreign metal are covered with the coating layer , and wherein the coating layer contains nickel or a nickel-cobalt alloy having a cobalt content of 50 mass% or more. plural separate portions filled with a foreign metal of which thermal conductivity is 80% or less of thermal conductivity of the mold copper plate or 125% or more thereof, the plural separate portions being formed as circular concave grooves having a diameter of 2 mm to 20 mm or as quasi-circular concave grooves having a circle-equivalent diameter of 2 mm to 20 mm, the grooves being provided on an inner wall surface of the mold copper plate, the plural separate portions being provided on an inner wall surface of the mold copper plate so that thermal resistance of the mold increases and decreases regularly and periodically in a width direction and a casting direction of the mold in vicinity of a meniscus, and the plural separate portions being formed at least in a region from the meniscus to a position located 20 mm or more lower than the meniscus, the region being whole or part of the inner wall surface, wherein, a ratio of Vickers hardness HVc [kgf/mm 2 ] of the mold copper plate to Vickers hardness HVm [kgf/mm 2 ] of filled foreign metal satisfies relational expression below: 0.3 ≤ HVc / HVm ≤ 2.3 and the ratio of the thermal expansion coefficient αc [μm/(m×K)] of the mold copper plate to the thermal expansion coefficient αm [μm/(m×K)] of the filled foreign metal satisfies relational expression below: 0.7 ≤ α c / α m ≤ 3.5 and wherein a coating layer is formed on the inner wall surface by a plating method or a thermal spraying method, the coating layer having a breaking elongation of 8% or more determined in accordance with "Metallic materials-Tensile testing" prescribed in JIS Z 2241, and the portions filled with the foreign metal are covered with the coating layer , and wherein the coating layer contains nickel or a nickel-cobalt alloy having a cobalt content of 50 mass% or more. <EOS>
