Abstract
To propose a structure of a small-sized airtight terminal capable of restraining a reduction in yield of steps of fabricating an airtight terminal and steps of integrating a piezoelectric vibrator and a mold structure of a surface mount type piezoelectric vibrator in correspondence with the airtight terminal, there is provided a surface mount type piezoelectric vibrator including 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 a stem of an airtight terminal, 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.
