Abstract:
A multi-layer laminate includes a glass panel unit, an intermediate film, and a transparent plate. The transparent plate is assembled to the glass panel unit via the intermediate film. The glass panel unit includes a first and second glass panel, and an evacuated space. The evacuated space is interposed between the first and second glass panel. A method for manufacturing the multi-layer laminate includes a step. The step includes exhausting a gas from a bag, loaded with the glass panel unit, the intermediate film, and the transparent plate, to cause the bag to shrink and thereby assembling, using the bag thus shrunk, the glass panel unit and the transparent plate via the intermediate film. The step includes raising a pressure inside the bag from a pressure at an initial stage of heating while increasing a temperature of the intermediate film to a predetermined temperature at which the intermediate film softens.
