Claim 4:
5. A pressurizing method for pressurizing and heating a target object mounted on a mounting base, the method comprising:
sandwiching the mounting base on which the target object is mounted between (i) an upper mold fixed on an upwardly-and-downwardly moveable base member and (ii) a heating lower mold, which is a heated lower mold, and heating the target object with heat from the heating lower mold while pressurizing the target object, a side mold being disposed around the upper mold and configured to form, when closely contacting with the mounting base, a hermetically closed space around the target object together with the upper mold and the mounting base;
sandwiching the mounting base between the upper mold and a cooling lower mold, which is a cooled lower mold, and cooling the target object while pressurizing the target object;
bringing, prior to the pressurization of the target object, the side mold into contact with the mounting base to form the hermetically closed space; and
sucking, prior to the pressurization of the target object, air from the hermetically closed space to bring a surrounding of the target object into a vacuum state.
