The present invention provides an aircraft including: a main wing; and a flight control surface that is deployed from the main wing in a first direction and in a second direction different from the first direction. In the aircraft, an end surface of the flight control surface facing the main wing when the flight control surface is not deployed is inclined with respect to the first direction or the second direction on at least one side of a longitudinal direction of the flight control surface, and a portion of the main wing facing the end surface is also inclined with respect to the first direction or the second direction in accordance with the end surface.
