Abstract:
An angular velocity detection element, comprising:a substrate;a pair of spaced support bodies arranged on the substrate and having at least a pair of support-side electrodes that face each other;a movable body, disposed between the support bodies, having at least a pair of movable-side electrodes facing the support-side electrodes; anda vibration generator for vibrating the movable body in one direction, the pair of support-side electrodes and the pair of movable-side electrodes being structured and arranged such as to constitute a pair of displacement detectors which detects the displacement of the movable body, and to constitute a pair of angular velocity detectors for detecting, as an angular velocity, a displacement perpendicular to the one direction in which the movable body vibrates when an angular velocity acts on the movable body.
