Abstract
An angular velocity sensor comprises a first sensor section (10), a second sensor section (20), and a first frame (31) in which a torsion bar (33) formed in the first sensor section (10) and a torsion bar (34) formed in the second sensor section (20) are connected. The torsion bars (33) and (34) are connected to the first frame (31) so as to be parallel to each other in the position in which their central axes are different to each other. With the configuration, the first and second sensor sections (10) and (20) can be prevented from being driven in phase, thus enabling accurate angular velocity to be detected.
