Abstract
A vibratory gyro piezoelectric vibrator includes a vibrating body having a laminate of piezoelectric layers stacked on each other in a lamination direction, and having a length extending in the lamination direction. The vibratory gyro piezoelectric vibrator uses longitudinal piezoelectric effects of the piezoelectric layers and operates such that a first bending vibration is excited in which the vibrating body bends in a width direction of the vibrating body substantially perpendicular to the lamination direction of the piezoelectric layers, and a Coriolis force is caused in response to the first bending vibration such that a second bending vibration is excited in which the vibrating body bends in a thickness direction of the vibrating body substantially perpendicular to both of the lamination direction and the vibration direction of the first bending vibration.
