A mold for forming a molded body from a slurry including an impermeable mold part having a cavity for retaining the slurry and a permeable mold provided on a side of a molding surface with a membrane filter. A method of forming a molded body from a slurry includes steps of introducing the slurry into a cavity of a mold including an impermeable mold part and a permeable mold part provided on a side of a molding surface with a membrane filter, and removing a solvent medium of the slurry through the permeable mold part. A pressure casting molding method of forming a high dense ceramic molded body by pouring a ceramic slurry into a mold through a pouring portion thereof and pressurizing the ceramic slurry on a side of the pouring portion while removing a solvent medium of the slurry on the other side of the mold through a permeable mold part of the mold. The method includes steps of filling a hydrophobic pressurizing medium in the pouring portion after pouring the ceramic slurry into the mold for pressurizing the ceramic slurry through the hydrophobic pressuring medium, and/or removing the solvent medium and/or removing the solvent medium through a membrane filter provided on a side of a molding surface of said permeable mold part of the mold.
