摘要： Provided are a steel cord and a single steel wire having excellent straightness quality for reinforcing tire and a method of manufacturing the steel cord and single steel wire. The steel cord and the single steel wire include a wire undergoing through a drawing process, a heating process performed in a state in which tension is applied to the wire, and a cooling process; and a winding portion on which the wire is wound, the winding portion having a diameter greater than a diameter of the wire, wherein, when an end of the wire that has been wound on the winding portion for six months to one year is fixed on a point and the wire is pulled down vertically to 400 mm, a distance between a first axis that is perpendicular to the point and an opposite end of the wire is 30 mm or less. The method of manufacturing the steel cord and single steel wire having excellent straightness quality for reinforcing tire includes: a wire preparing process, a heating process, a cooling process, and a winding process.
