| 摘要 |
A vibrating gyroscope (10) includes: a piezoelectric substrate (14) polarized oppositely in the thickness direction; two divided electrodes (16) provided at one main surface of said piezoelectric substrate (14); a common electrode (18) provided at the other main surface of said piezoelectric substrate (14); drive means (30) for applying a drive signal between said two divided electrodes (16) and said common electrode (18) to vibrate said single piezoelectric substrate (14) under a bending mode; and detection means (36) for detecting a signal generated between said two divided electrodes (16). <IMAGE> |
