Abstract

See full text

An angular velocity sensor includes fixing units, a base portion, beam portions that support the base portion with respect to the fixing units, driving vibrating arms connected to the base portion, and detection vibrating arms connected to the base portion. When a width of a detection frequency band is set to f1 [Hz], a resonance frequency in a rotational vibration mode in which the base portion rotates and vibrates around a detection axis with respect to the fixing units in association with the deformation of the beam portions is set to f2 [Hz], and a detuning frequency is set to f3 [Hz], the relation of f1
