Abstract
A capacitive physical quantity sensor includes a first substrate, a movable electrode, a fixed electrode, and a second substrate. An auxiliary electrode is disposed on a portion of the second substrate to face the movable electrode and the auxiliary electrode has a facing area that faces the movable electrode. The facing area in a case where the movable electrode is displaced in one direction is different from the facing area in a case where the movable electrode is displaced in an opposite direction opposite to the one direction. The physical quantity is detected based on a capacitance, which is generated corresponding to the interval between the fixed electrode and the movable electrode, and a capacitance, which is generated corresponding to an interval between the facing area of the movable electrode and the auxiliary electrode.
