Abstract
Provided is an angular velocity sensor including a plurality of angular velocity detection units each outputting a different detection result, and including a common driving circuit to drive the angular velocity detection units. The angular velocity detection units of the angular velocity sensor of the present invention are configured to have different driving amplitudes when being driven by a driving signal at the same frequency.
