ABSTRACT:
A tuning-fork type piezoelectric vibratory gyroscope includes a tuning fork having two arms and a base portion integrally formed with the two arms and having electrodes, and a supporting base supporting the base portion of the tuning fork. An adhesive layer joins the base portion and the supporting base together so that the tuning fork and the supporting plate are elastically integrated within a temperature range in which the gyroscope is used.
