ABSTRACT:
An angular velocity sensor includes a tuning-fork oscillator having a pair of arms jointed by a trunk, the pair of arms extending in parallel to each other, first and second driving piezoelectric elements arranged only on one surface of the trunk with a gap therebetween in an extending direction of the arms, and angular velocity detecting piezoelectric elements arranged on surfaces of the arms in parallel with the one surface of the trunk on which the first and second piezoelectric elements are arranged.
