密性も維持出来る。[Prior Art] Piezoelectric vibrators and piezoelectric oscillators using ceramic packages have been announced. Generally, a conductive film such as silver palladium is applied to an insulating substrate such as ceramic. Although the insulating substrate and the lid made of ceramic or the like are sealed via glass frit containing a large amount of lead, there is a risk that the conductive film will be eaten away by the glass frit, resulting in poor conductivity. Subcomponents of the conductive film include PbO, SiO 2 and the like, but they account for around 10%. Furthermore, the bond between the glass frit and the conductive film is not very good. Therefore, in order to prevent the conductive film from being eaten away, a Si-based glass coat, which has a higher melting point than glass frit, is baked on top of the conductive film, and then the glass frit is baked on to prevent the conductive film from being eaten away. Furthermore, since the conductive film and the glass coat, and the glass coat and the glass frit are bonded well, high airtightness can be maintained.

It is a piezoelectric container with no film erosion and good bonding.
