An object is to provide a resin material having high strength and high vibration-damping property. A resin material includes a matrix resin and carbon nanocoils contained therein. The carbon nanocoils have electrical conductivity, so that the matrix resin containing them can easily convert a vibration energy generated in the resin material into heat and thereby damp the vibration energy in a short time. In addition, since the carbon nanocoil is in a coiled form, vibration-damping property can be enhanced in comparison with that of conductive materials such as carbon nanotube and graphite.
