ABSTRACT:
A vibrating gyroscope includes a vibrator constructed by bonding a first piezoelectric substrate polarized in the thickness direction and a second piezoelectric substrate polarized in the same direction as the first piezoelectric substrate, through an intermediate electrode. The vibrator includes two first strip electrodes, provided on one main face of the first piezoelectric substrate in the longitudinal direction of the first piezoelectric substrate so as to be spaced from each other, and a second strip electrode provided substantially on the whole of the second strip electrode. The vibrator includes an electrode film formed on the whole of one end-face thereof by a sputtering method.
