PROBLEM TO BE SOLVED: To provide a thermal spraying method and a casting mold for continuous casting which improve the adhesion property and wear resistance that heretofore by the technique of thermarly spraying to the casting mold for a continuous casting machine and without executing fusing treatment. SOLUTION: After a part or the entire part of the casting mold consisting of copper or copper alloy is subjected to nickel plating of 0.05 to 2mm in thickness, this surface is blast-treated to a roughness of 30 to 50μm in Rmax, and next, the entire casting mold is preliminarily heated to 100 to 250 deg.C, and then, nickel-group self-fluxing alloy or WC-Co alloy of 0.1 to 1mm in thickness is quickly thermally-sprayed. The component of the nickel-group self-fluxing alloy at this time point is preferably 66 to 70% Ni, 15 to 20% Cr, 3 to 5% B, 3 to 5% Si, 0.8 to 1.2% C, 2 to 3% Fe, and the balance of inevitable impurities or the component of WC-Co is 12 to 20% Co and 80 to 88% WC.
