PROBLEM TO BE SOLVED: To provide a recyclable thermoplastic elastomer composition where an electrical conductivity is imparted and workability is good. SOLUTION: An electro conductive thermoplastic elastomer composition is formed by dispersing a carbon nanotube to a thermoplastic elastomer material where a rubber is blended to a thermoplastic elastomer, and (a) a rubber portion of the thermoplastic elastomer material is crosslinked by a resin crosslinking agent to have compression set of 30% or less, (b) a blended amount of the rubber is in a ratio of 225 to 400 parts by weight based on the 100 parts by weight of the thermoplastic elastomer and (c) the carbon nanotube has a diameter of 70 nm or less. The composition has a smooth side surface formed with the shape where graphen sheets are rounded and is such a composition that a plurality of layers composed of graphen sheets are arranged in a concentrically circular state.
