Next, as shown in FIG. 2(b), the sealing material 4A is placed on the side wall portion 3b, and the glass cover 5A is placed thereon. The glass cover 5A has an outer peripheral portion 5Aa that protrudes outward from the side wall portion 3b when placed on the side wall portion 3b. The outer peripheral portion 5Aa is placed on the jig side wall portion 6b and covers the jig recess 6c. Since the jig 6 has the encapsulating material 6e, the glass cover 5A can be preferably fixed. Next, the outer peripheral portion 5Aa of the cover glass 5A is sucked by the vent hole 6d of the agitator 6, and the cover glass 4A is adhered to the seal member 4A on the side wall portion 3b. Since the inside of the jig recessed portion 6c is decompressed, the glass cover 5A can be more reliably adhered to the sealing material 4A. Thereby, the airtightness of the hermetic package 1 can be effectively improved, and the reliability can be effectively improved. Preferably, the inside of the container 3 is also decompressed by the above suction. Thereby, the hermetic package 1 can be hermetically sealed in the container 3 by decompression, and the airtightness can be improved. In addition to this, the element 2 is less likely to react with oxygen or moisture, and therefore reliability can be improved. The container 3 can also be filled with an inert gas. For example, the inside of the recessed portion 3c on which the glass cover 5A is placed may be replaced with an inert gas, and then the glass cover 5A may be sucked. By filling the inside of the container 3 with an inert gas in advance, the hermetic package 1 can be a hermetic package in which the inside of the container 3 is replaced with an inert gas, and the reliability can be further improved. Next, as shown in FIG. 2(b), the laser light L is irradiated from the glass cover 5A side to the sealing material 4A. Thereby, the sealing material 4A is melted, and the side wall portion 3b is joined to the glass cover 5A. At this time, the sealing material layer 4 shown in Fig. 1 is formed. Next, the hermetic package 1 shown in Fig. 1 is obtained by cutting the outer peripheral portion 5Aa of the cover glass 5A. The size of the glass cover 5 after the cutting is not particularly limited, and it is preferable to cut so that the outer peripheral edge of the side wall portion 3b coincides with the outer periphery of the glass cover 5 in plan view. Thereby, the hermetic package 1 can be preferably miniaturized. Further, as in the modification of the manufacturing method shown in FIG. 3, the jig 16 having the spring member 16f in the portion where the container 3 is placed on the bottom portion 16a of the jig may be used. In this case, in the step of sucking the outer peripheral portion 5Aa of the cover glass 5A, the container 3 is pressed to the side of the cover glass 5A by the spring member 16f. Therefore, the cover glass 5A can be more reliably adhered to the sealing material 4A. Hereinafter, the effects of the present invention will be described in more detail by comparing the manufacturing method of the hermetic package of the present embodiment with a comparative example. Fig. 4 is a front cross-sectional view for explaining a comparative example of a method of manufacturing a hermetic package. As shown in FIG. 4, in the comparative example, the glass cover 25 was pressed to the container 23 side by the glass member 25 by which the press member 27 containing the glass plate was mounted. Thereby, the glass cover 25 and the sealing material 24A are adhered. However, in this case, the portions of the glass cover 25 that the pressing member 27 is in contact with each other form the problems of the above 1) to 3). On the other hand, in the method of manufacturing a hermetic package of the present embodiment, the cover glass 5A is adhered to the sealing material 4A by suction of the cover glass 5A. Therefore, the package having high airtightness can be efficiently produced without causing the problems of the above 1) to 3). In the above embodiment, the glass cover is sucked by sucking the outer peripheral portion of the cover glass, but the present invention is not limited thereto. For example, a method may be adopted in which a vent hole is formed in advance in a side wall portion of the container, and a glass lid is sucked by venting the inside of the container in which the glass lid is placed through the vent hole, and the side wall portion is joined after joining. The vent is sealed.
