    摘要： An extrusion molding apparatus and an extrusion molding method is provided that permits deformation of molded body to be prevented and a sound extrusion molded body to be obtained even in the case where a soft extrusion molded body having low rigidity in a direction perpendicular to extrusion direction is molded. An extrusion molding apparatus 1 comprises a screw extruder 12 that kneads a molding raw material 80 and extrudes an extrusion molded body 8 from a molding die 11, and a conveying apparatus 3 that supports said extrusion molded body 8 extruded continuously from the screw extruder 12 and conveys same in the extrusion direction. The screw extruder 12 has an inclination angle θ between the extrusion axis A and horizontal axis H in the range of 15° to 85°. The conveying apparatus 3 is constructed so as to move a reception stage 32 that supports said extrusion molded body 8 extruded along said extrusion axis A on the outer circumferential surface thereof, generally in parallel to said extrusion axis A. The inclination angle θ is preferably in the range of 30° to 75°.
