ABSTRACT:
A vibrating gyroscope 10 includes a vibrator 12. The vibrator 12 has a regular triangular prism-shaped vibrating body 14, and piezoelectric elements 16a, 16b and 16c are formed on side faces of the vibrating body 14. Resistors 26 and 28 are connected to the piezoelectric elements 16a and 16b, and an oscillation circuit 30 and a phase correction circuit 32 are connected between the resistors 26, 28 and the piezoelectric element 16c. An opposite phase signal against a driving signal is supplied to a ground terminal of the vibrator 12. Output signals of the piezoelectric elements 16a and 16b are supplied to a differential circuit 36.
