Abstract: An angular velocity sensor includes a substrate, a detector including a movable detection electrode and a fixed detection electrode opposed to the movable detection electrode, and a driver adapted to drive the detector. The movable detection electrode is supported by a first spring that is elongated parallel to a Y axis from a first turned-back part, and a second spring that is elongated parallel to the Y axis from a second turned-back part. The first and second springs are fixed at first and second anchors. The first turned-back part is closer to the second spring than the first anchor. The detector includes a first surface opposed to the first spring, and a second surface disposed closer to the first spring than the first surface.
