1. An angular velocity sensor comprising:

  • a reference vibrator supported so as to generate reciprocating rotational vibration about a first rotation axis as a center;

    a detection vibrator supported by the reference vibrator so as to generate reciprocating rotational vibration about a second rotation axis, which is different from the first rotation axis, as a center;

    a reference vibration generating unit for allowing the reference vibrator to generate reciprocating rotational vibration; and

    a detection unit for detecting a displacement amount of the detection vibrator with respect to the reference vibrator, which is in association with the reciprocating rotational vibration of the detection vibrator.
