Abstract
The vibrator includes for example, a triangular prism shaped vibrating body. On each of three side faces of the vibrating body, piezoelectric elements are formed respectively. The vibrating body makes bending vibration by giving a driving signal to one or two piezoelectric elements. The vibrator is used in a vibratory gyroscope. In this case, for example, one piezoelectric element is used for vibrating the vibrator. When a rotating force is applied to the vibratory gyroscope, a Coriolis force is exerted to produce output voltages on the remaining two piezoelectric elements corresponding to the rotational angular velocity.
