A hot press apparatus for hot pressing a thin plate-like workpiece, includes a base 1, lower and upper heating plates 4, 16, a flat lower mold member 8, lower and upper frame members 10, 18, a workpiece taking-out unit 7, an upper press plate 12, a heat-resistant and stretchable film member 19 covering the lower end portion of the upper frame member 18, a heat medium M filled in a heat medium-filling space above the film member, and a driving unit 13. A film member-horizontally holding member 20 substantially horizontally holds the film member while preventing the film member from hanging, while keeping it at a substantially constant position as viewed in a horizontal direction. The workpiece is hot pressed with the film member by applying pressure to the heat medium inside the heat medium-filling space while the film member is prevented from expanding radially outwardly at an outer periphery thereof.
