A compressive residual stress portion having a compressive residual stress from a surface of a wire to a first depth is formed between end turn portions of a coil spring. The first portion of the end turn portion is always in contact with a spring seat. The second portion contacts the spring seat when the load applied to the coil spring is large, and is separated from the spring seat when the load is small. The third portion is always separated from the spring seat. In the end turn portion, in a region including the second portion, a deep residual stress portion is formed by ultrasonic shot peening. The deep residual stress portion has a compressive residual stress from a surface of the wire to a second depth deeper than the first depth.
