1. A method for manufacturing a multi-layer laminate,
the multi-layer laminate comprising:
a glass panel unit;
an intermediate film; and
a transparent plate assembled to the glass panel unit via the intermediate film,
the glass panel unit including:
a first glass panel;
a second glass panel; and
an evacuated space interposed between the first glass panel and the second glass panel,
the method comprising:
a step of 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,
wherein the step includes raising a pressure inside the bag stepwise or continuously 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.
