Abstract
The angular velocity detection element includes: a substrate; a pair of spaced support bodies arranged on the substrate and having support-side electrodes that face each other; a movable body, disposed between the support bodies, having a pair of movable-side electrodes facing the support-side electrodes; and a vibration generator for vibrating the movable body in one direction. The support-side electrodes mounted on the support bodies and the movable-side electrodes that are mounted on the movable body are arranged such that the movable-side electrodes face the support-side electrodes. A pair of displacement detectors detect the displacement of the movable body in one direction when the vibration generator imparts a vibration in one direction to the movable body, and a pair of angular velocity detectors detect, as an angular velocity, a displacement perpendicular to the one direction in which the movable body vibrates when the angular velocity acts on the movable body.
