A tail boom capable of creating propulsive force during forward flight to increase the forward speed is provided. A tail boom producing a force that cancels out a torque effect due to the Coanda effect by forcing airflow generated by a propeller disposed on an upstream side downward through a slit penetrating in the thickness direction and provided at a lower part of one side surface is configured such that the airflow generated by the propeller contributes to the propulsive force during forward flight.
