ABSTRACT:
To provide a small-sized and highly sensitive oscillation gyroscope, an oscillation gyroscope 20 includes a first through a seventh piezoelectric substrate 24a through 24g, the first through the seventh piezoelectric substrates 24a through 24g are respectively polarized in the same direction and are integrally laminated, a first lead electrode 26a, a second lead electrode 26b, a first driving electrode 28a and a second driving electrode 28b are formed in the first and the second piezoelectric substrates 24a and 24b, the first lead electrode 26a is connected to the first driving electrode 28a and the second lead electrode 26b is connected to the second driving electrode 28b, first through fifth divided electrodes 32a1 through 32e1 and 32a2 through 32e2 are formed in the third through the seventh piezoelectric substrates 24c through 24g, first ones of the first through the fifth divided electrodes 32a1 through 32e1 are mutually connected to one another and also to a third lead electrode 26c and second ones of the first through the fifth divided electrodes 32a2 through 32e2 are mutually connected to one another and also to a fourth lead electrode 26d.
