Abstract: A vacuum lamination device for laminating a lamination member includes a base plate having an uneven surface contacting the lamination member for placing the lamination member, a frame member fixed to the base plate and having a discharge port for evacuating a processing space, and a cover member for hermetically sealing the processing space in the lamination process. The lamination member is placed on the uneven surface, and the cover member is placed so as to cover the lamination member. Then, a gaseous material in the processing space is evacuated through the discharge port while heating the processing space.
