の空間が機能上影響を与えるという問題点があった。In the conventional hermetic sealing by welding using heat generated by laser light or electric resistance, an unwelded portion is generated between a welded portion and the inner diameter of a package. The part existed electromagnetically as a space. In the development of a package used in a high frequency band, there was a problem that the space between the welded portion and the inner diameter of the package had a functional effect because the wavelength was short.

る。In the embodiment, the cap 1 has a squeezing structure, and has a bulge corresponding to the inner diameter portion of the package.
The reason why the shim 2 is arranged therein is to prevent a gap from being formed in the welded portion when the shim 2 enters between the cap 1 and the package 3 if the cap 1 is flat.
