A leading edge member of an airfoil of an aircraft has an outside wall defining a wing span and a deicing device for circulating hot air in the direction of the wing span of the airfoil. The device includes a hot air distribution duct extending inside the leading edge member in the direction of the span of the foil. The duct has a plurality of orifices distributed over at least part of its length. A hot air supply communicates with one end of the distribution duct. The hot air supply is connected by ducts located outside the leading edge member to at least one propulsion engine of the aircraft.
