密容器として用いることができる。[Example 1] Fig. 1 shows the structure of a piezoelectric vibrator using a tuning fork-shaped crystal vibrating piece as an example of the present invention. It is plated 2. The molten solder plating is performed by solder dip, solder reflow, etc. Similarly, the molten solder plating 6 is also applied to the plug body, which is made up of the two leads 3 and the metal ring 5 on the outer periphery of the glass portion 4 through which they pass. ing. The tuning fork type crystal vibrating piece 7 is fixed by remelting the solder 6 of the lead 3 and soldering it. At this time, the molten solder plating 2.6 exists as a gasket that is hermetically sealed by tightly fitting the case 1. It is sufficient that the molten solder plating is applied only to the enclosing part 8, but in reality, as shown in the figure, it is present all over the interior or in the vicinity of the enclosing part, and it also exists in parts other than the role of the packing. When solder plating is performed by electroplating, the organic components incorporated into the plating are released as gas from the above-mentioned excess area, resulting in a deterioration of the vacuum. However, in the present invention, since molten solder plating is used, no gas is released, so a high vacuum can be maintained and a high quality crystal resonator can be obtained. Further, the molten solder plating 2 of the case l may be applied only near the enclosing part 8, or it may be on the outer surface.If the case l has the molten solder plating 2, the plug body does not have the molten solder plating 6 and is replaced with nickel. The tuning fork-shaped crystal vibrating piece 7 may be fixed to the lead 3 using a conductive adhesive or the like, or the metal ring 5 of the plug body may be plated with hot-dip solder. In this case, the solder plating will be pushed out when it is sealed, so it is preferable that the case l side be coated with molten solder plating 2.The piezoelectric vibrating piece may not be a tuning fork type crystal vibrating piece, but it may be a strip type crystal vibrating piece. A vibrating piece, a piezoelectric vibrating piece made of ceramic, lithium tantalate, etc. may also be used.
In addition, molten solder plating can be used with solders such as eutectic solder, high-temperature solder, and silver-containing solder, and even if it is not a piezoelectric vibrator, it can be used as an airtight container for parts that require airtightness, such as filters, sensors, and ICs. Can be done.

質とすることができる。An airtight container that exhibits a similar effect is a combination of a cylindrical case made of a cladding material made of a metal material and a solder material with solder on the inside, and the above-mentioned plug body. The cladding material has the structure shown in FIG. 3, and is manufactured from a metal material 31 such as nickel silver and a plate solder material 32 by a rolling method or the like. Plate solder does not contain organic components, unlike solder deposited by electroplating. Alternatively, it may be a cladding material made of a metal material plated with molten solder.Therefore, a high vacuum can be obtained without gas release. In a piezoelectric vibrator using this airtight container, the vibrating piece is kept in a high vacuum and can be of high quality without any organic components attached.
