A flat wire that is not susceptible to changing into a helical shape over time is provided. The flat wire (10) is composed of a large number of carbon fibers (31) impregnated with a thermosetting resin. A cross section of the flat wire (10) is rectangular, has an inner surface (12) that always faces inward and an outer surface (11) that always faces outward, and has a helical form with a fixed diameter in the longitudinal direction. The lengths of the carbon fibers (31) constituting the flat wire (10) gradually become longer toward the outer surface (11) from the inner surface (12). L'invention concerne un fil plat qui n'est pas susceptible de prendre une forme hélicoïdale au cours du temps. Le fil plat (10) est composé d'un grand nombre de fibres de carbone (31) imprégnées par une résine thermodurcissable. Une coupe transversale du fil plat (10) est rectangulaire, présente une surface interne (12) qui est toujours tournée vers l'intérieur et une surface externe (11) qui est toujours tournée vers l'extérieur, et présente une forme hélicoïdale comportant un diamètre fixe dans le sens longitudinal. Les longueurs des fibres de carbone (31) constituant le fil plat (10)) deviennent progressivement plus longues vers la surface externe (11) à partir de la surface interne (12).
