ABSTRACT:
An angular velocity sensor of a horizontally located type, in which influence of a translational acceleration applied thereto from a lateral direction is readily removed and a fixed portion thereof is easily fixed, is provided. It includes a fixed portion fixed to the top surface of a sensor element supporting portion of a casing, an upper detection arm portion and a lower detection arm portion respectively connected to the fixed portion on sides opposite to each other and extending along a plane parallel to the top surface of the sensor element supporting portion, and a pair of upper vibration arms connected to the fixed portion with the upper detection arm portion in between. The fixed portion includes one or more slits extending at least in a direction intersecting with the extending direction of the upper detection arm portion.
