Abstract:
1. A surface mount type piezoelectric vibrator comprising: an airtight terminal including a stem in a ring-like shape comprising an electrically conductive material, a lead arranged to penetrate inside of the stem and electrically insulted from the stem, and a filling member for sealing the lead at inside of the stem hermetically; a piezoelectric vibrating piece having a pair of exciting electrodes, a first electrode of the pair of exciting electrodes being electrically connected to the lead, and a second electrode thereof is being electrically connected to the stem; a case of a bottomed cylinder type fixed to the stem to cover the piezoelectric vibrating piece to form an airtight space; a first external electrode terminal, the first electrode and the first external electrode being electrically conductive through the lead; a second external electrode terminal, the second electrode and the second external electrode being electrically conductive; and a mold resin which was molded on surfaces of the case and the airtight terminal to expose end portions of the respective first and second external electrode terminals.
