Abstract: A method for manufacturing an electrical component, comprising: an armature (1) formed by a polymeric plastic material and an organometallic additive and comprising a support arm (4), with a winding (2) formed directly on the surface of the support arm (4) by a conductor track (10) forming turns. According to the invention, in order to obtain a winding with a high density of turns, with a precise arrangement which varies little over time, while making it possible to have a winding design with any desired geometry, the manufacturing method comprises laser engraving of the support arm (4), for engraving an initiator track forming the turns of the winding (2) and where the organometallic additive is locally activated. The method then comprises metallizing the initiator track with a conducting metal so to form the conductor track (10) according to the turns formed by the initiator track.
