Zusammenfassung:	PROBLEM TO BE SOLVED: To suppress energy loss, to perform transfer molding in a short period of time, and to improve durability of an apparatus.SOLUTION: A transfer molding process performing transfer molding of a resin made sheet 25 held between a first mold 9 and a second mold 10 that are arranged to be opposed to each other by heating at least one of the molds, and a cooling process for cooling the resin made sheet 25, are performed. The cooling process is performed by a first cooling process for cooling the resin made sheet 25 in a state where pressurization at a first set value smaller than pressurization force at the transfer molding process is maintained, and by a second cooling process for cooling the resin made sheet 25 in a state where pressure is removed to a second set value smaller than the first set value.
