PROBLEM TO BE SOLVED: To provide an extrusion molding machine which scarcely generates a crack in a molded product and can obtain the molded product having high strength, and to provide a molding method using the same. SOLUTION: In the extrusion molding machine having a cylindrical rectifying part 20 for rectifying the flow of a plastic material provided between a supply screw 11 and a mold die 13, a plurality of flow channels for connecting an inlet (a-a) and an outlet (b-b) is formed in the rectifying part 20 to divide the flow of the plastic material. The plastic material flowing in the center part in the inlet (a-a) of the rectifying part 20 is altered to the peripheral edge part in the outlet (b-b) of the rectifying part 20 and the plastic material flowing in the peripheral edge part in the inlet (a-a) of the rectifying part 20 is altered to the center part of the outlet (b-b) of the rectifying part 20.
