The purpose of the present invention is to efficiently supply power to a power storage device (battery 260), and efficiently and safely deliver goods when goods are being transported by an unmanned flying body 3. The unmanned flying body 3 travels along a flight path and sequentially lands at one or more delivery sites where a load (such as goods, packages, relief supplies) is delivered to the receiving side and one or more power receiving sites where a non-contact power supplying facility (charging station 2) is provided. Upon landing at a landing site which serves as the power receiving site and the delivery site, the unmanned flying body 3 causes a power receiving device 20 to receive the power to be used for charging the battery 260 through a non-contact power supply, while causing a delivery device 280 to deliver the load 41 to the receiving side. The unmanned flying body 3 restricts the delivery of the load 41 to the receiving side if authentication is not successful. The delivery device 280 captures and stores an image of when delivering the load 41 to the receiving side.
