ABSTRACT:
An angular velocity sensor of a horizontally located type, which can easily remove the translational acceleration influence thereto from the lateral direction, is provided. It includes a fixed portion fixed to the surface of a sensor element supporting portion of a casing, an upper detection arm and a lower detection arm, each of them being connected to the fixed portion on sides opposite to each other and extending along a plane parallel to the surface place of the sensor element supporting portion, and a pair of upper vibration arms connected to the fixed portion in such a manner as to form a pair of arms with the upper detection arm in between and extending in a direction parallel to the extending direction of the upper detection arm.
