ABSTRACT:
An angular velocity detector includes an angular velocity detecting element having a vibrating body arranged in a base substrate to be vibrated on a surface horizontal with respect to the base substrate. The angular velocity detecting element detects an angular velocity around an axis perpendicular to the base substrate based on a vibration of the vibrating body. In the angular velocity detector, a circuit substrate is bonded to a first surface of the base substrate through an adhesive, and a second surface of the angular velocity detecting element is electrically connected to the circuit substrate through a bonding wire. Furthermore, the adhesive is partially arranged on the first surface of the base substrate at least at a portion corresponding to a bonding portion of the bonding wire on the second surface of the base substrate. Therefore, a wire bonding can be easily accurately performed.
