The invention relates to a curved structural part (110) formed of a composite material having a fibrous reinforcement with continuous fibres and of which the cross section comprises at least two wings (10, 12), said fibres (3) extending from one wing to the other, said structural part comprising a variation in the width of its cross section (112) parallel to the local radius of curvature (203). The structural element resulting from the assembly of parts according to the invention thus has local widenings of the cross section at the connections between the parts constituting a structural element, such as an aircraft fuselage frame, and widenings at the connection with the floor profiles (120) in the case of using such a profile for the construction of an aircraft fuselage structure. The invention also relates to a method of manufacturing such a part.
