ABSTRACT:
A vibrating gyroscope 10 includes a regular quadrangular prism-shaped vibrator 12. The vibrator 12 includes, a first piezoelectric base plate 14a and a second piezoelectric base plate 14b, which are polarized reversely each other in a direction of thickness. On a main surface of the first piezoelectric base plate 14a, two divided electrodes 16, 16 are formed in laterally spaced relationship. On a main surface of the second piezoelectric base plate 14b, a common electrode 18 is formed. Between the first piezoelectric base plate 14a and the second piezoelectric base plate 14b, a dummy electrode 20 is formed. One output terminal of an oscillation circuit 30 as a driving means is connected to the two divided electrodes 16, 16 of the vibrator 12, via resistors 32a and 32b. Another output terminal of the oscillation circuit 30 is connected to the common electrode 18 of the vibrator 12. The two divided electrodes 16, 16 of the vibrator 12 are respectively connected to a non-inverting input terminal and an inverting input terminal of a differential amplifier circuit 36 as a detecting means, via resistors 34a and 34b.
