Abstract:
    The surface mount type piezoelectric vibrator includes: an airtight terminal provided with annular stem, lead disposed through the stem and insulative to the same, and filling members arranged in the stem to seal the lead; 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 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 electrically conductive to the first electrode by way of the lead, a second external electrode terminal electrically conductive to the second electrode, and a mold resin molded to be formed on surfaces of the case and the airtight terminal to expose end portions of the respective first and second external electrode terminals.
