To provide the manufacturing method for a ceramic molding, the demolding of which can be easily performed and which is easily manufactured.

This method is to manufacture a ceramic molding by casting ceramic molding slurry in the cavity of a gypsum mold. In this case, this method consists of a process for preparing the gypsum mold consisting of a core 2, in which air supplying tubes 24 for supplying air in the cavity 5, and the like, a process for supplying a moisture 1 to the gypsum mold, a process for molding a ceramic molding through the deposition of slurry 71 on a molding surface 50 by casting the ceramic molding slurry 71 in the cavity and a process for demolding by forcing the air within the gypsum mold through the air supplying tubes 24 so as to force the moisture 1 supplied in advance in the gypsum mold between a molding surface and a ceramic molding.
