This spring used for a suspension device for a vehicle is provided with: a metal wire material which constitutes a spring section and which has a cover layer provided on the surface thereof; and a seat section which is subjected to a load acting on the spring section, is formed from an elastically deformable material, and is bonded to the cover layer by an adhesive. The difference between the hardness of the seat section and the hardness of the adhesive is greater than the difference between the hardness of the adhesive and the hardness of the cover layer.
