ABSTRACT:
A vibrating gyroscope having a vibratable body in the form of a triangular prism, piezoelectric elements formed on side surfaces of the vibrating body and having the same vibration characteristics and a detection circuit having two input terminals connected to two of the piezoelectric elements to detect the difference between the outputs from the two piezoelectric elements, the two detection piezoelectric elements being selected such that the difference between their outputs with respect to a change in ambient atmosphere temperature is the smallest.
