摘要： An oscillating angular speed sensor includes a detector, a driving portion, and a separating portion. When an angular speed is generated while the detector is driven to oscillate by the driving portion, Coriolis force is applied to the detector. Therefore, the angular speed is detected based on a capacitance variation in accordance with a variation of an interval between a movable electrode and a fixed electrode of the detector. The separating portion is distanced from the detector and the driving portion, and is configured to separate a first space accommodating the detector and a second space accommodating the driving portion.

摘要： An angular velocity sensor includes a vibrator, a support substrate, an anchor section, a connection beam section, a driving section, and a detection section. The vibrator includes an inner vibrator and an outer vibrator, which vibrate in opposite circumferential directions when driven by the driving section. The connection beam section couples the vibrator to the anchor section, and is elastic in a z-direction and a circumferential direction. The connection beam section includes first connection beams, each of which is coupled to the outer vibrator at one end and is coupled to the inner vibrator at the other end, and second connection beams, each of which is coupled to a vibration node of a corresponding first connection beam at one end and is coupled to the anchor section at the other end.
