Claim:
1. A yaw-rate sensor, comprising: a substrate having a main extension plane to detect a yaw rate about a first direction extending either parallel to the main extension plane or perpendicular to the main extension plane; a drive device; a first Coriolis mass, the drive device being configured to drive at least a part of the first Coriolis mass in a direction parallel to a drive direction extending perpendicular to the first direction, wherein in the case of the yaw rate about the first direction, at least the part of the first Coriolis mass undergoes a Coriolis acceleration parallel to a detection direction extending both perpendicular to the drive direction and perpendicular to the first direction; and a first compensating mass having a coupling with the first Coriolis mass via a first connection to the substrate, such that a deflection of the first Coriolis mass in a direction parallel to the detection direction caused by the Coriolis acceleration leads to a deflection of the first compensating mass in an opposite direction.
