A vane for a turbomachine comprising a blading made of composite material with fibrous reinforcement densified by a matrix and an integrated metal leading edge, the blading extending in a longitudinal direction, the leading edge being formed by a metal foil overmolded onto the blading, said metal foil being asymmetrical and having a lower wing and an upper wing which extend respectively on the lower and upper faces of the blading while matching an aerodynamic profile of the vane,
- wherein one of the lower wing and the upper wing has a positioning portion extending in the longitudinal direction, said positioning portion having a flat inner face and an increasing thickness away from the leading edge, said positioning portion being housed in a correspondingly shaped groove in the blading,
- and wherein the positioning portion extends over a length comprised between 50% and 80% of the length of the corresponding wing measured between the leading edge and a trailing edge opposite the leading edge.
