Abstract
Abstract A heat process device according to the present invention includes a film-like heating body serving as a heat source for a heat transfer plate on which an object to be processed is mounted and heated. Therefore, the heat process device can be excellent in controlling the heating temperature. It can also apply a uniform heat process to the object. Further, it can be made small in size and easy to operate.
