Provided is a flat wire the helical shape of which is resistant to change even with the passage of time. A flat wire (10) is composed of a multiplicity of carbon fibers (31) impregnated with a thermosetting resin. The flat wire (10), the cross section of which is rectangular, has an inner surface (12) facing inward at all times, an outer surface (11) facing outward at all times, and has been shaped into helical form of constant diameter in the longitudinal direction. Carbon fibers (31) constituting the flat wire (10) are of gradually increasing length from the inner surface (12) toward the outer surface (11) of the wire.
