    Abstract: The flocked helical spring includes a spring body, a cationic electrodeposition coating layer disposed on the surface of the spring body, an adhesive layer disposed on the surface of the cationic electrodeposition coating layer, and a flocking layer composed of flocking fillers fixed to the adhesive layer. The surface roughness Rz of the cationic electrodeposition coating layer is 19.6 μm or greater. The method for producing a flocked helical spring includes a cationic electrodeposition coating process of performing a cationic electrodeposition coating treatment on a spring body to form a film of an electrodeposition coating material on the surface of the spring body; an adhesive coating process of coating an adhesive containing a surface roughening solvent on the surface of the film; a flocking process of bonding flocking fillers to the surface coated with the adhesive; and a baking process of heating the spring body adhered with the flocking fillers.
