To provide a novel casting molding method for slurry by which a molded body having uniform density is efficiently molded at short time.

A mold 1, into which a slurry S of ceramics is injected, is placed on a turntable 2 and thereafter the turntable 2 is rotated to exert centrifugal force to the slurry S in the above-mentioned mold 1 and also self-excited vibration in the three-dimensional direction is caused in the turntable 2 and centrifugal molding is performed. Thereby, thixotropic properties of slurry are enhanced and the slurry becomes an easily fluidized body and a molded body having uniform density is efficiently molded at short time.
