[Solution] Up and down, and left and right are controlled by providing an aerial drone (20) with a vertical transceiver which oscillates infrared or laser light towards the upper and lower walls in the vertical direction and receives the reflected light; and a horizontal transceiver which oscillates infrared or laser light towards the left and right wall in the cross-section perpendicular to the direction of travel, and receives the reflected light. The inspection device is provided with: a camera (22) which images the inner wall of the duct and acquires the imaging data; a current position determining means for determining the current position of the aerial drone (20) in the duct; and an imaging data recording means which links the imaging position to the imaging data from the camera (22) and records the same.
