To provide a coil spring with excellent fatigue resistance and corrosion fatigue resistance.SOLUTION: A coil spring according to one embodiment is formed from a wire wound in a spiral manner, and has a seat turn part and an effective part. The surface of the wire in the seat turn part has a first region, and a second region that is softer than the first region. Further, in a circumferential direction centered on an axis of the wire, the second region is formed over a wider area than the first region.SELECTED DRAWING: Figure 2
