Abstract
An angular velocity sensor comprises a driving element, a detecting element, and a feedback element, all of which are disposed on an element forming face of an oscillator. An electrostatic capacitance of the feedback element is set to be equal to that of the detecting element. As a result, a synchronous detection circuit can reduce the offset signal due to a phase difference between signals from the feedback element and the detecting element.
