Abstract:
A vibrating gyroscope comprising:a bar-shape vibrator including a first piezoelectric substrate polarized in a thickness direction, a second piezoelectric substrate polarized in the same thickness direction, laminated to the first piezoelectric substrate, an intermediate electrode provided between the first piezoelectric substrate and the second piezoelectric substrate, a first strip electrode formed on one main face of the first piezoelectric substrate, and a second strip electrode formed on one main face of the second piezoelectric substrate;an interconnection electrode to connect electrically the intermediate electrode to a portion of at least one of the first strip electrode and the second strip electrode, the portion being divided from the remaining portion of the at least one of the first strip electrode and the second strip electrode;a driving means for driving the vibrator in the thickness direction; anda detecting means for detecting a displacement produced by bending of the vibrator, wherein the portion and the remaining portion are divided from one another in a width direction and the first strip electrode is divided in a longitudinal direction of the vibrator and is connected to both the drive means and the detection means, the second strip electrode is connected to the drive means, and the intermediate electrode is connected to a reference potential.
