Abstract
PURPOSE:To cheaply improve the reliability of the air tight sealing by metallizing the circumference of the small hole of an insulation substrate, supporting a crystal vibrating reed with a lead terminal to penetrate and solder a lead wire and bonding the above-mentioned insulating substrate and a case with the resin. CONSTITUTION:A lead terminal 3 is derived from the internal part of a case through an insulation substrate 1, fixed by soldering 4 to a metallizing part 2 due to the Ag of the insulation substrate 1 and airtight-sealed. At the tip of the lead terminal 3 in the internal part of the case, a supporting part exists, a crystal piece 7 to arrange an electrode 9 to front and rear is held by conducting adhesives 8 and conducted electrically with the lead terminal 3. Further, a case 6 is sealed to the insulating substrate 1 with adhesives 5 and the airtight-sealed crystal vibrator is formed. Thus, since a hermetic sealing is not used, the reliability of an initial characteristic and a long-term characteristic is not worsened and the titled vibrator can be manufactured cheaply.
