PROBLEM TO BE SOLVED: To provide a method for simply and economically manufacturing a casting mold for precision casting, which casting mold has the practically sufficient strength enough to bear a load during its carriage. SOLUTION: The casting mold for precision casting is made by the following first, second, third steps. The first step comprises making an intermediate laminated body having a cavity corresponding to a wax pattern by removing the wax by the lost wax process. The second step is for making a hardened body having the intermediate laminated body integrally therein by setting the intermediate laminated body made in the first step in a vessel and by pouring slurry of self-curing mold material between both of them. The third step is to obtain the casting mold for precision casting by baking the hardened body made in the second step. COPYRIGHT: (C)2006,JPO&NCIPI
