Abstract
A vibrating gyrosensor includes a support substrate on which a wiring pattern having lands is formed. A vibrating element is mounted on a surface of the support substrate. The vibrating element includes a base part having a mounting surface on which a number of terminals connectable to the lands is formed. A vibrator part integrally projects from a side of the base part and has a substrate-facing surface coplanar with the mounting surface of the base part. The vibrator part has a first electrode layer, a piezoelectric layer, and a second electrode layer which are laminated on the substrate-facing surface. The vibrator part vibrates when an AC signal is applied between the first and second electrode layers. The central electric field strength of the AC signal is set at a position shifting to the positive direction from the center of a hysteresis loop of the piezoelectric layer.
