PROBLEM TO BE SOLVED: To improve a production speed without deteriorating the quality of a molded plate. SOLUTION: A raw material heated/kneaded by an extruder is discharged to a molding die 10 having a core body 40 as an extrusion ground, the ground is molded in a prescribed thickness, and a hollow part is formed in the ground. In the slow cooling part 21b of a molding chamber, the core body 40 has a channel 42 for a cooling medium and is formed to be able to cool the molded ground gradually from the inside. A molded plate extruded from the molding die 10 is received by a receiving means, and a molded plate producing speed is increased.
