복합 센서(1)는, 제 1 물리량을 검출하는 제 1 센서(10)와, 제 1 센서와 다른 종류의 센서로서, 제 1 물리량과 동일 또는 제 1 물리량과 상관되는 제 2 물리량을 검출하는 제 2 센서(21∼25)와, 제 1 센서의 검출 결과 및 제 2 센서의 검출 결과를 상호 비교함으로써 제 1 센서와 제 2 센서의 적어도 한쪽의 고장 진단을 실시하는 내부 제어부(51)를 구비한다. A composite sensor (1) includes a first sensor (10) configured to detect a first physical quantity; a second sensor (21 to 25) as a sensor of a different type from the first sensor, the second sensor being configured to detect a second physical quantity identical to or correlating with the first physical quantity; and an internal control unit (51) configured to perform failure diagnosis for at least one of the first sensor or the second sensor by comparison between a detection result of the first sensor and a detection result of the second sensor.
