PURPOSE: To manufacture a ceramic thin member free from a defect by enabling molding of the thin member, by sticking slurry to a core material by making use of a material having shrink or disappear properties as the core material.

CONSTITUTION: Slurry 20 stuck to a core material 4 is held as a molded body 22 in a form stuck to the core material 14 through dryness. The core material 14 is caused to shrink or disappear with a solvent and the ceramic molded body 22 is obtained under that condition. As the molded body 22 is obtained through adhesion of the slurry 20 to the core material 14 and the core material 14 is removed through the solvent, damage of the molded body 22 at the time of demolding is not generated. As the title method is of the molding formed by making use of the slurry 20, it is hard to generate a defect at the time of use of a kneaded matter of resin and a ceramic material.
