Zusammenfassung:	PURPOSE:To manufacture a plurality of molded bodies of very fine pieces in a certain quality with a high efficiency and at a low cost. CONSTITUTION:A product cavity 36, a molding tool 28 provided with an introduction inlet 30 and a discharge passage 38 communicated with said cavity, a mixing tank 10 and a molding device provided with a passage 26 having a pump 24 middle way are used. Slurry formed by mixing a solvent with its boiling point lower than the normal temperature with very fine pieces to be molded is stored in the mixing tank, and while the slurry is pressurized by the pump up to 10kg/cm or above and introduced into the cavity 36 through the introduction inlet 30, a solvent in the cavity is discharged out of a discharge outlet 38. The solvent is flowed out of the discharge passage while lowering its pressure, and very fine pieces are pressure molded by pressure gradient in the cavity between the introduction inlet and the discharge passage.
