[PROBLEMS] To provide a drone (unmanned aerial vehicle) for dispersing a medicine, which has a simple structure and minimizes the scattering of a medicine outside a field without additional equipment or complicated control. [MEANS FOR SOLVING PROBLEMS] A medicine spraying nozzle and a rotor (preferably a two-stage rotor) are provided, and the medicine spraying nozzle is located below the rotor and centered at a point offset a predetermined distance backward with respect to the traveling direction of the rotor rotation axis. The rotor is positioned below a circular area having a radius of 90% of the radius of the rotor and on a straight line with a depression angle of about 60 degrees rearward in the traveling direction from a horizontal line passing through the rotation axis of the rotor. To provide a drone for spraying a medicine, which actively utilizes the airflow of the spray. The position of the medicine spray nozzle may be dynamically controllable.
