    Abstract: PROBLEM TO BE SOLVED: To achieve small-sized formation of a piezoelectric vibrator while preventing exciting electrodes provided at both faces of the piezoelectric vibrating piece from being short-circuited to each other and enabling to fabricate the piezoelectric vibrating piece easily. SOLUTION: There is provided a piezoelectric vibrator 1 including a case 3 in a shape of a bottomed cylinder having an opening portion 3a and having conductivity, a ring 12 substantially in a cylindrical shape press-fitted to the opening portion 3a of the case 3 and having conductivity, one piece of a lead 13 inserted to the ring 12 and having an inner lead portion 15 and an outer lead portion 16, a filling member 14 having an insulating property for sealing an interval between the lead 13 and the ring 12 in airtight, and a piezoelectric vibrating piece 2 which is constituted by substantially a plate-like shape arranged at the inside of the case 3 and includes exciting electrodes 8, 9 at both faces thereof and in which the exciting electrode 8 is supported by the inner lead portion 15 by being subjected to bump connection with the inner lead portion 15 of the lead 13 and the exciting electrode 9 is subjected to wire bonding with the ring 12.
