Abstract
The present invention provides a cheap angular velocity sensor capable of detecting angular velocity with high precision by using a vibration mode which cannot be set by external vibration. The angular velocity sensor includes: a vibrator () formed as a solid of revolution and made of a magnetostrictive material; a supporter () disposed on an axis of the vibrator () and supporting the vibrator () at a position where the axis crosses the surface of the vibrator (); an excitation coil () for generating a magnetic field along a radial direction around the axis as a center in the vibrator (), thereby making the vibrator () vibrate in the radial direction; a detection coil () which is disposed apart from the vibrator () and detects a magnetic flux change caused by a change in the vibration of the vibrator () which occurs depending on angular velocity.
