Abstract
An angular velocity measuring device includes an angular having a mounting surface on which a velocity detection element, element-side drive electrodes and element-side detection electrodes are provided and a ground electrode is disposed between the drive electrodes and the detection electrodes. On the top surface of a multilayer substrate, substrate-side drive electrodes and substrate-side detection electrodes are provided and a ground electrode is disposed between the drive electrodes and the detection electrodes. The electrodes of the angular velocity detection element are connected to the electrodes of the multilayer substrate and the two ground electrodes are arranged to face each other. Furthermore, on the top surface of the multilayer substrate, drive wirings connected to the drive electrodes are provided and, inside the multilayer substrate, detection wirings connected to the detection electrodes are provided. Ground wirings sandwiching the detection wirings in the thickness direction are disposed in the multilayer substrate.
