ABSTRACT:
An angular velocity detector includes vibrator made of piezoelectric material and having a pair of arms. A pair of driving electrodes are attached to the arms in order to generate vibrations in the arms. A pair of detecting electrodes, which are attached to the arms, detect the vibrations of the arms. Therefore, the pair of driving electrodes can cause the arms to vibrate uniformly and stably, so that a S/N ratio of the angular velocity sensor can be improved.
