Abstract
A resonance frequency adjustment module is disclosed forming a MEMS sensor for detecting an angular velocity. The resonance frequency adjustment module includes a movable electrode; a fixed electrode facing the movable electrode to form a capacitor; and an elastic body supporting the movable electrode so as to be displaceable in one direction. The movable electrode and the fixed electrode have surfaces facing each other to form a capacitor, and the surface can be inclined to a displacement direction. A region sandwiched between the movable electrode and the fixed electrode has a volume fixed region where the volume is not decreased by movement of the movable electrode.
