Claim:
A forming mold for obtaining a molded body with a hollow portion by molding a slurry comprising inorganic powders, a disperse medium, and a gelling agent, comprising: an outer mold having a first hole, which opens into the upper surface of the outer mold and extends downward from said opening, formed therein; an upper mold stacked on said outer mold and having a second hole, which passes through in a vertical direction, formed therein, wherein, in a state where the upper mold is stacked on the upper surface of said outer mold, the lower opening of said second hole and the opening of said first hole are connected such that the lower opening of said second hole is included in the opening of said first hole; and an inner mold having an insert in a shape of a rod, which is inserted into the first and second holes from above; wherein, in said upper mold, a slurry reservoir, which leads to the upper opening on the second hole and retains said slurry, is formed; and said forming mold is configured such that, in an assembly-completed state where said upper mold is stacked on the upper surface of said outer mold and said insert is inserted in said first hole and said second hole, a space formed between the inner wall of said first hole and the surface of said insert is used as a molding space for molding said slurry and said slurry poured into said slurry reservoir is filled in said molding space through a space formed between the inner wall of said second hole and the surface of said insert.
