Abstract
A laminating apparatus that prevents partial protrusion of a film during pressing and ensures the uniformity of the thickness of a resulting laminate is provided. The laminating apparatus includes a pressing device for pressing a substrate and a film (a workpiece). The pressing device includes a press block movable back and forth, a pressing plate mountable to the press block, a plurality of heat sources (cartridge heaters) capable of heating the pressing plate, and a control system set up to perform heating control on the heat sources. The heat sources are arranged so as to be able to separately heat a central portion of the pressing plate and a peripheral portion thereof annularly surrounding the central portion.
