Abstract
A piezoelectric vibrator uses aluminum nitride as piezoelectric material and thickness sliding vibration as the primary vibration. A polarization direction of the primary vibration is along the longitudinal direction of its vibrating element. This vibrator eliminates undesired resonance, caused by a width of the vibrating element, from a vicinity of a resonance frequency of the primary vibration. Vibrating element has width W and thickness H defined as follows: 2.0≦W/H≦4.0 or 4.3≦W/H≦5.7 or 6.2≦W/H≦7.8 or 8.2≦W/H≦9.8.
