Here disclosed is an angular velocity sensor with much accuracy, not allowing other vibration components to mix into the Coriolis force component. The angular velocity sensor contains a first through a fifth beams: the first, the second, and the third beams have a length of substantially the same and disposed in a substantially parallel arrangement on a substantially the same plane-with the first beam placed between the second and the third; the fourth connects each one end of the first through the third, while the fifth connects each other end of them. The first beam is supportively fixed at its mid-portion. The first beam serves as a detector; the second serves as a driver; and the third serves as a monitor.
