Then, the laminate is placed into a rubber bag, and preliminarily bonding is carried out at about 70° C. to 110° C. under vacuum suction. Preliminary bonding can be carried out using a method other than this method, and the following method can also be adopted. The above-described laminate is heated in an oven at 45° C. to 65° C., for example. Subsequently, this laminate is pressed by a roll at 0.45 to 0.55 MPa. Then, the laminate is heated in an oven again at 80° C. to 105° C., and is then pressed again by a roll at 0.45 to 0.55 MPa. Preliminary bonding is completed in this manner.
Then, permanent bonding is performed. The preliminarily bonded laminate is permanently bonded using an autoclave at a pressure of 8 to 15 atm and at 100° C. to 150° C., for example. Specifically, permanent bonding can be performed under the conditions of 14 atm of pressure and a temperature of 135° C., for example. The interlayer 13 is bonded to the glass plates 11 and 12 through preliminary bonding and permanent bonding described above. Then, the interlayer 13 that protrudes from the outer glass plate 11 and the inner glass plate 12 is cut off.
Then, the heating wire 8 is formed on the inner surface of the inner glass plate 12 using the above-described method.
