A method for manufacturing a continuous casting mold in which cracking and spalling are less likely to occur in a filling laminate. The method includes filling a plurality of concave portions formed on an inner surface of a copper-made mold copper plate or a copper alloy-made mold copper plate used for continuously casting steel at least in a region including a meniscus position of molten steel in a casting process with a metal having a thermal conductivity different from that of the mold copper plate.
