Abstract
An angular velocity sensor includes: a board in the form of a flat plate; a rotational vibrator extended to the right and left from a central axis vertical to the board at the center of rotational vibration over the board and supported at the location of the central axis by rotational supporting beams so as to be rotationally vibrated; a first vibrator located on the left side of the rotational vibrator and supported by first supporting beams; a second vibrator located on the right side of the rotational vibrator and supported by second supporting beams; a rotational vibration generator for vibrating the second vibrator backward and forward when the first vibrator is vibrated forward and backward by giving rotational vibration to the rotational vibrator; a first displacement detector for detecting displacement of the first vibrator vibrated to the right and left when an angular velocity is applied around the central axis of the rotational vibrator in the state that rotational vibration is given to the rotational vibrator by the rotational vibration generator; and a second displacement detector for detecting displacement of the second vibrator vibrated to the right and left when an angular velocity is applied around the central axis of the rotational vibrator in the state that rotational vibration is given to the rotational vibrator by the rotational vibration generator.
