Abstract
A vibrating gyroscope includes a vibration member in which first and second piezoelectric substrates are joined together. On the outside main surface of the first piezoelectric substrate, a first external electrode divided into six electrode sections is formed. On the outside main surface of the second piezoelectric substrate, a second external electrode is formed. By removing a part of the electrode sections disposed at the center, a capacitance difference C(L)-C(R) between the capacitance C(L) formed between one of the electrode sections disposed at the center and the second external electrode, and the capacitance C(R) formed between another electrode section disposed at the center and the second external electrode is adjusted.
