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 physical quantity sensor includes a detection unit outputting a detection signal corresponding to a vibration of a vibrating element in an angular velocity sensor, and a self-diagnostic unit self-diagnosing a detection environment of an acceleration sensor and the angular velocity sensor on a basis of the detection signal outputted by the detection unit.
