Abstract
A vibrating gyroscope includes a vibrating body which is formed into, for example, a square loop. A section of the vibrating body is formed into, for example, a square. Driving piezoelectric elements are formed on upper and lower faces of one piece of the vibrating body. Detecting piezoelectric elements are formed on outer and inner side faces of a piece of the vibrating body whereon the driving piezoelectric element is formed. On a piece adjoining the piece whereon the driving piezoelectric element is formed, the detecting piezoelectric elements are formed. By applying a signal to the driving piezoelectric elements, the vibrating body is subjected to bending vibration, and by measuring an output voltage of the detecting piezoelectric elements, a rotational angular velocity is detected.
