1. An angular-velocity detection apparatus, comprising:

  • a substrate;

    a vibratory body provided on the substrate, the vibratory body being capable of displacing in a vibration axis direction and a detection axis direction which intersect at right angles to each other;

    vibration generation means for vibrating the vibratory body in the vibration axis direction in response to a driving signal;

    displacement detection means for detecting the amount of displacement of the vibratory body when the vibrating body is displaced in the detection axis direction in response to an angular velocity applied about a detected axis intersecting at right angles to the vibration axis and the detection axis and when the vibratory body is vibrated in the vibration axis direction by the vibration generation means; and

    corrective-vibration generation means for causing the vibrating body to vibrate for correction in the detection axis direction in response to a correction signal.
