The invention provides an aircraft lifting surface with a monolithic main supporting structure (14) of a composite material comprising an upper skin (21) including at least a part of the upper aerodynamic profile of the leading edge (11) and/or of the trailing edge (15), a lower skin, a front spar (18), a rear spar (20), a plurality of leading edge ribs and/or a plurality of trailing edge ribs. This main supporting structure allows a weight and cost reduction of aircraft lifting surfaces. The invention also provides a manufacturing method of said monolithic main supporting structure (14).
