To provide a method for manufacturing a ceramics molded product having general-purpose properties, capable of eliminating the adverse effect caused by the volatilization of an organic solvent corresponding to various highly concentrated slurries low in viscosity and capable of manufacturing the ceramics molded product homogenous as a whole, in manufacturing the ceramics molded product by a cast molding method using the organic solvent as a dispersing medium.

In the method for manufacturing the ceramics molded product having a casting process for injecting a slurry, which is prepared by mixing a ceramics powder, a dispersant and a binder with the dispersing medium comprising the organic solvent, in a porous casting mold and a liquid absorbing process for absorbing the dispersing medium in the slurry injected in the casting mold by the casting mold, the vapor pressure of the organic solvent in the slurry is held to 3 kPa or below during the period over the casting process and the liquid absorbing process. Alternatively, the casting mold is placed in a hermetically sealed space filled with organic solvent vapor.
