ABSTRACT:
An angular velocity sensor is provided with an oscillator including a pair of drive arms, a base portion coupled to one end of each drive arm, and a flexible arm extending from the base portion in a direction opposite from the drive arms. This angular velocity sensor is also provided with a driving member which oscillates the pair of drive arms in an approaching or separating direction, and a distortion detecting member which detects a distortion of the flexible arm in the oscillating direction of the drive arms.
