ABSTRACT:
An oscillation type angular velocity sensor includes an oscillator, as exciting device for exciting the oscillator, a detecting device for detecting the direction of oscillation of the oscillator which occurs by a Coriolis force acting on the oscillator when an angular velocity is applied thereto and a correction device adhered to a portion of the oscillator for correcting the direction of the oscillation of the oscillator by varying the elasticity of the portion of the oscillator.
