ANGULAR VELOCITY DETECTION DEVICE

An angular velocity detecting apparatus includes a sensor chip having an angular velocity sensor installed therein, wherein the angular velocity sensor includes two mass elements which are driven in a drive direction in opposite phase with each other, and detects an angular velocity based on an oscillation of the mass elements in a direction perpendicular to the drive direction, the angular velocity detecting apparatus comprising: two acceleration sensors provided on the sensor chip, each of the acceleration sensors having a mass element which can oscillate in a single axis direction in a plane parallel to a substrate surface of the sensor chip, wherein the acceleration sensors are arranged in such a positional relationship that the mass elements of the acceleration sensors are oscillated in opposite phase with each other at the time of a rotational vibration of the sensor chip while the mass elements of the acceleration sensors are oscillated in phase with each other at the time of a translational vibration of the sensor chip.
