PROBLEM TO BE SOLVED: To provide a material for highly accurately manufacturing a ceramic shaped object by three dimensional molding.SOLUTION: A method for manufacturing a molding material 7 used for three-dimensional molding comprises a step of dispersing a ceramic fine particle 72 in a liquid resin, a step of curing a mixture obtained in the dispersion step, and a step of pulverizing the cured product into particles (that is, molding particles 71) having a larger particle size than the ceramic fine particle 72 to obtain the molding material 7. Thereby, it is possible to provide a material for highly accurately manufacturing a ceramic shaped object by three-dimensional molding.SELECTED DRAWING: Figure 1 【課題】セラミックス造形物を３次元造形にて高精度に製造するための材料を提供する。【解決手段】３次元造形に用いられる造形材料７の製造方法は、セラミックス微粒子７２を液状の樹脂中に分散させる工程と、当該分散工程にて得られた混合物を硬化させる工程と、当該硬化工程にて得られた硬化物を、セラミックス微粒子７２よりも粒径が大きい粒子（すなわち、造形粒子７１）に粉砕して造形材料７を得る工程とを備える。これにより、セラミックス造形物を３次元造形にて高精度に製造するための材料を提供することができる。【選択図】図１
