Abstract
A method for fabricating a piezoelectric vibrator includes inserting a filling member formed with a through hole inside of a ring having a substantially cylindrical shape, and inserting one piece of a lead to the through hole of the filling member to project from both sides of the ring. The method further includes sintering the filling member along with the ring and the lead to integrate in an airtight manner, subjecting an exciting electrode of the piezoelectric vibrating piece to a bump connection with an inner lead portion of the lead projected from the ring, subjecting another exciting electrode on a side of the piezoelectric vibrating piece opposed to the other exciting electrode to wire bonding with the ring, and press-fitting the ring to an opening portion of a case and sealing the piezoelectric vibrating piece connected with the inner lead portion inside of the case in an airtight manner.
