    摘要: A thermoforming apparatus includes a frame material having a housing region and a frame edge portion of a base material being a thermoforming target; and a heating plate having a square shaped heating surface in a plan view, and a frame section which protrudes toward the frame material from the outer peripheral edge of the heating surface, the frame section being contactable with the frame edge portion of the frame material, wherein the heating plate is provided with vacuum holes opening to the outer peripheral portion of the heating plate in a plan view at a perimeter of the frame section in the heating surface, and before adsorbing the sheet disposed between the frame edge portion of the frame material and the outer peripheral edge of the heating plate to the heating surface, a gap is included in at least a portion between the sheet and the heating surface.
