SEALED CONTAINER OF CRYSTAL OSCILLAOR OR THE LIKE

PURPOSE:To improve the utilizing rate of an inner space, by providing a thin oxide coating film on an inner wall of a cover of a container sealing a crystal oscillator or the like so as to avoid an electric failure due to the contact between electronic components contained therein and the cover inner wall. CONSTITUTION:An electrode 24, terminal metal fixtures 21, 22 and a jumper 23 and the like are formed incorporatedly on a bottom plate 20 made of an insulator such as glass of the sealed container sealing the electronic components such as a crystal oscillating chip 10. A step 25 is fitted to the upper end of the jumper 23 of the bottom plate 25, and electrodes 10a, 10b of the oscillating chip 10 are bonded to the tip with a conductive adhesives to hold the oscillating chip 10 mechanically. A metallic cover 11 is provided around the oscillating piece 10 and a flange 11a of the cover 11 is sealed airtightly to a flange 20a of the bottom plate 20 with a low melting point glass layer 26. The inner wall of the cover 60 of the sealed container constituted in this way is provided with the thin oxide coating film 61 in advance so as to prevent the oscillating piece 10 contained therein from contacting with the inner wall of the cover 60 for avoiding electrical failure, allowing to use the inner space effectively.
