The invention provides a fluoroelastomer composition that can be crosslinked at an industrially sufficient rate without the use of a graphene having specific surface properties and can provide a fluoroelastomer molded article having higher tensile strength and better abrasion resistance than conventional fluoroelastomer molded articles even though having a similar tensile modulus to conventional fluoroelastomer molded articles. The fluoroelastomer composition contains a fluoroelastomer that contains a crosslinkable group-containing monomer unit and an elongated sheet-shaped graphene. The graphene exhibits a ratio (L/W) of a maximum length (L) and a width (W) of 2 to 10.sup.5, and the graphene exhibits a ratio (L/T) of the maximum length (L) and a thickness (T) of 110.sup.1 to 110.sup.7.

An object of the present invention is to provide a resin material that yields a resin molded article which has not only a low volume resistivity but also excellent weldability and cleanliness and whose volume resistivity is unlikely to be increased even when subjected to an SPM cleaning treatment and the like. The present invention provides a composite resin material that contains a modified polytetrafluoroethylene and carbon nanotubes and has an average particle diameter of 500 m or smaller.
