The present invention refers to a method for manufacturing a leading edge (1) of an aircraft lifting surface, the leading edge having a leading edge skin (2) and a supporting structure (3) including at least two spars span-wise arranged and fixed internally to the leading edge skin. In the method of the invention, the supporting structure (3) is obtained from a single laminate (4) of plies of composite material, which is conformed in such a manner that in a cross-sectional view of the same, the laminate includes a trapezoidal configuration which forms a front spar (5) and a rear spar (6) of the supporting structure. The invention also refers to a leading edge obtained by the above-described method. Since the supporting structure of the leading edge is obtained from a single component, namely the laminate (4), the manufacturing method is simplified and production costs are significantly reduced.
