To solve problems that ceramic powder is not sufficiently filled in a molding space in a molding die for a bottomed ceramic tube molded product, resulting in the generation of defective molding at the bottom of the molded product, and occurrence of cracks.

The bottomed ceramic tube molding die is provided with a cylindrical mold 5 corresponding to the outer shape of the molded product, a cylindrical rubber mold 1 inside the mold 5 having a dividable bottom part 2, a core metal 3 corresponding to the inner diameter of the molded product, and a lid body 4 airtightly sealing the opening part for the molding space 7 formed by the rubber mold 1 and the core metal 3 for filling the ceramic power therein. A vent port 8 is formed in the core metal 3 and the center axial direction of the lid body 4, allowing the ceramic powder to be evenly and sufficiently filled, even in a thin and long molding space, without applying cutting work to the molded product, to provide a ceramic molded product of a desired shape.
