<P>PROBLEM TO BE SOLVED: To provide an isostatic pressing die enabling a cutting period of time of a cylindrical ceramic molding to be shortened by reducing a range to be cut during cutting after pressing, and forming the cylindrical ceramic molding having uniform density. Ž<P>SOLUTION: The isostatic pressing die 100 is provided with: a columnar core metal 1; a lid portion 2 disposed on end 1a of the core metal 1; a bottom portion 3 disposed on the other end 1b of the core metal 1; and a cylindrical molding rubber die 4 disposed from the lit portion 2 to the bottom portion 3 so as to form a space between the die 4 and the core metal 1. The surface of the lid portion 2 facing the core metal 1 side and the surface of the bottom portion 3 facing the core metal 1 side are planes orthogonal to the core metal 1. The hydrostatic-pressure molding die 100 further includes a cylindrical bottom side rubber ring 7 disposed in contact with the bottom portion 3 and the inner surface 4a of the molding rubber die, and a cylindrical lid side rubber ring 8 disposed in contact with the lid portion 2 and the inner surface 4a of the molding rubber die.
