A moving object detection device comprising: an ultrasonic sensor that detects the moving object; and a detection means that determines and detects that the moving object is present when the presence of the moving object is detected by both of the sensors. (2) In the moving object detection device according to claim 1 of the utility model registration, the infrared sensor is a piezoelectric element having a pyroelectric effect, and the piezoelectric element is excited by applying a voltage thereto to generate an ultrasonic wave. A moving object detection device that emits a sound wave and vibrates when reflected ultrasonic waves are incident, so that the moving object detection device doubles as the ultrasonic sensor.
