PROBLEM TO BE SOLVED: To improve CI (crystal impedance) value and impact resistance, without degrading the aging characteristics. SOLUTION: At a piezoelectric vibrator, where an electrode formed to be a case accommodating the piezoelectric vibrator and a holding-connecting electrode section of the electrode formed to be the piezoelectric vibrator is held and connected by conductivity adhesive, the surface of the holding-connecting electrode section formed to be the piezoelectric vibrator is formed with a metal layer, having proper adhesiveness with silicone based conductivity adhesive, and the surface of other electrode section is formed with a gold layer.
