A cell 4 obtained by putting together a pair of substrates 1 and 2 with a sealant interposed is laid on a laying stage inside a housing unit 30 which is roughly of a shape of frame of a box, pressurized by a pressure plate 43 by applying compressed air pressure to an elastic plate 41 from the opposite side while the cell 4 is being held, and as they are being pressurized, evacuation is performed through an opening of the sealant 3, and the whole housing unit is gradually heated inside a thermostatic chamber while maintaining this condition, thereby curing the sealant without causing any deformation of substrates, distortion or peeling of the sealant, or change in the preset gap or miss-alignment between the substrates.
