PROBLEM TO BE SOLVED: To provide an extrusion molding machine capable of hardly generating defects on the surface of a ceramic molded body, the ceramic molded body molded by using the same, and its manufacturing method it. SOLUTION: The extrusion molding machine 1 has an extruder 12 for extruding a ceramic material 20 consisting of a mixed body of ceramic particles, a resin component and a solvent to its tip side, and a mold 11 for molding ceramic materials 20 arranged at the tip side of the extruder 12 and molding the ceramic material 20. The mold surface 110 of the mold 11 for molding is surface-treated so that a difference of the surface free energy between the mold surface and the ceramic material 20 becomes≥10 mJ/m<SP>2</SP>.
