Abstract
An angular velocity sensor for detecting angular velocity by converting deflection caused by the coriolis force into an electrical signal. The sensor includes a vibratory member having at least three main surfaces including a first main surface having a driving transducer provided thereon, and second and third surfaces substantially perpendicular to the first main surface respectively, and being parallel to each other, the second and third main surfaces having detecting piezoelectric transducers, respectively. Additionally, support members are connected to the second and third main surfaces to respectively support vibration-steady points of the vibratory member. At least one longitudinal end portion of the vibratory member has a cross-section in such a manner that a length between the second and third main surfaces is shorter than a length of the first main surface. In this manner, the sensitivity of the angular velocity sensor is improved.
