ABSTRACT:
A vibrating gyroscope includes a piezoelectric substrate polarized oppositely in the thickness direction. Two divided electrodes are provided at one main surface of the piezoelectric substrate and a common electrode is provided at the other main surface of the piezoelectric substrate. An oscillation circuit applies a drive signal between the two divided electrodes and the common electrode to vibrate the single piezoelectric substrate under a bending mode and a differential amplifier circuit detects a signal generated between the two divided electrodes.
