To provide a mold for molding ceramics capable of manufacturing a ceramics molded product almost uniform in thickness.

This mold for molding ceramics is used in a cold isotropic pressure method for filling the cavity (7) formed between a core (2) and a rubber mold (1) with a ceramics raw material and pressing the outer surface side of the rubber mold (1) to mold the ceramics molded product under pressure and equipped with the core (2), the rubber mold (1) installed so as to form the cavity (7) along with the core (2), a stand on which the core (2) is fixed and the rubber mold (1) is installed, a vibrator (6) attached to the stand in order to almost uniformly fill the cavity (7) with the ceramics raw material and the outer frame (3) installed around the rubber mold (1) to suppress the vibration with a predetermined amplitude or above of the rubber mold (1).
