Abstract: Within a housing portion in which a recessed portion is formed, a circuit board is arranged on the bottom surface of the recessed portion, through a first connecting member. An acceleration sensor is stacked on the circuit board, through a second connecting member. Hence, sections that function as three or more springs, i.e., an anti-vibration portion, the first connecting member, and the second connecting member, are situated between an angular velocity sensor and the acceleration sensor. For this reason, transmission of vibration of the vibrating element in the angular velocity sensor to the acceleration sensor can be restricted, and reduction in the detection accuracy of the acceleration sensor can be restricted.

Abstract: A capacitive physical quantity sensor includes a first substrate a movable electrode, a fixed electrode, a second substrate, a signal applying unit a C-V conversion circuit, and an auxiliary electrode. The auxiliary electrode is disposed from a portion of the second substrate which faces the movable electrode to a portion of the second substrate which faces a displaceable region of the movable electrode. The signal applying unit applies a predetermined potential to the auxiliary electrode at the time of self-diagnosis, to thereby increase a density of electric force lines generated between the fixed electrode located in a direction of displacing the movable electrode and the movable electrode.

Abstract: In an acceleration sensor, a semiconductor layer is provided with a rod-shaped weight portion that passes through a center of a frame portion, extends in a second direction, and is connected to the frame portion through a first beam portion. A first-direction movable electrode and a second-direction movable electrode are provided on the weight portion. According to the above configuration, because a mass of the first- and second-direction movable electrodes can be applied to the vicinity of a center of the frame portion, and a rotational moment can be reduced. Thus, detection accuracy can be restrained from being reduced.

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.
