Abstract:
1. An angular velocity detector comprising: an angular velocity detecting element including a base substrate having a rectangular shape, and a vibrating body arranged in the base substrate to be vibrated on a surface horizontal with respect to the base substrate, wherein 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; a circuit substrate laminated with the angular velocity detecting element to be bonded to a first surface of the base substrate of the angular velocity detecting element through an adhesive; and a bonding wire through which a second surface of the base substrate of the angular velocity detecting element, opposite to the first surface, is electrically connected to the circuit substrate, wherein the adhesive is partially arranged on four corner areas of the first surface of the base substrate corresponding to a bonding portion of the bonding wire on the second surface of the base substrate.
