ABSTRACT:
A physical quantity sensor includes: a substrate; an angular speed sensor disposed on the substrate; and an acceleration sensor disposed on the substrate. The angular speed sensor includes an oscillator capable of oscillating by a driving force and displaceable in accordance with a Coriolis force attributed to an angular speed of the oscillator. The acceleration sensor includes a movable portion displaceable in accordance with an acceleration applied to the acceleration sensor. The oscillator has a driving direction, which is not parallel to a displacement direction of the movable portion. The physical quantity sensor having the angular speed sensor and the acceleration sensor detects both of the angular speed and the acceleration with high accuracy.
