ABSTRACT:
Film bodies are provided on opposing surfaces of an upper platen and a lower platen, and a frame is provided on the lower platen. The frame forms a forming room when the upper platen and the lower platen are brought close to each other. One film body is fixed on a heater having a given flexibility and rigidity. The upper platen includes a flow path through which a coolant is circulated. A recessed portion is formed on the lower surface of the upper platen under the film body. The material to be formed is pressurized by the film bodies due to a pressure reduction caused by depressurizing the forming room without reducing its capacity, in a state in which the film body is separated from the recessed portion and heated by the heater. Then, the material is cooled while in tight contact with the recessed portion.
