FLAT WIRE AND METHOD FOR PRODUCING SAME.

摘要

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).
