A carrying device that carries a piece of freight by hanging it from an unmanned aerial vehicle via a flexible member and, in moving the freight toward the ground with the vehicle hovering, confirms the freight has landed, and removes it. The device includes: an unmanned aerial vehicle including a plurality of propellers each drivable into rotation by a motor; a support wire mounted on the vehicle and made of a flexible member configured to support a piece of freight; and a landing detector configured to detect a landing of freight supported on the wire when moved from a space in air toward a ground. The landing detector is preferably configured to detect the landing of the freight based on at least one change in a load acting on the vehicle as a weight, a weight acting on the support wire, and a distance from the freight to the ground.
