Zusammenfassung:	일 실시 형태에 따른 코일 스프링은, 나선형으로 권취된 소선에 의해 형성되고, 좌권부 및 유효부를 갖고, 상기 좌권부에 있어서의 상기 소선의 표면은, 상기 유효부에 있어서의 상기 소선의 표면보다도 부드러운 영역을 갖고 있다. According to an embodiment, a coil spring is formed of a wire which is helically wound, and includes an end turn portion and an effective portion, and a surface of the wire in the end turn portion includes an area which is softer than a surface of the wire in the effective portion.
