1. An object detection device comprising:
a transmission and reception unit configured to transmit a transmission wave including an ultrasonic wave having directivity in a direction parallel or substantially parallel to a traveling direction of a movable body, and receive a reflected wave from an object;
a determination unit configured to determine presence or absence of an abnormality based on a predetermined reference distance and a downward distance between the transmission and reception unit and an object present below the transmission and reception unit in a vertical direction, the downward distance being calculated based on a reflected wave of an ultrasonic wave of the transmission wave traveling downward in the vertical direction from the transmission and reception unit; and
an output unit configured to output information regarding the abnormality.
