In this method, a wire is spirally formed, a first terminal and a second terminal connected to a power source capable of supplying an AC current are attached to the wire, and an AC current is caused to flow through the wire via the first terminal and the second terminal to heat the wire in a temperature distribution in which the temperature of an inner diameter side portion of the wire is higher than the temperature of an outer diameter side portion. In the wire after the forming and before the heating, the inner diameter side portion has a greater tensile residual stress than the outer diameter side portion. Due to the heating, the tensile residual stress of the inner diameter side portion is reduced, and the hardness of the inner diameter side portion is reduced more than the hardness of the outer diameter side portion is.
