Abstract: The present invention provides a composite obtained by processing a resin composition including a thermoplastic resin, multi-walled carbon nanotubes. The multi-walled carbon nanotubes have an average diameter of 10 nm-3 nm and an Id/Ig of 0.6 or more. The walls of the multi-walled carbon nanotubes consist of 10 or more layers of graphene. The rate of residual length of the carbon nanotubes present in the composite is 40% or more. The composite has improved mechanical properties without deterioration of conductivity. Due to these advantages, the composite can be used to manufacture various molded articles.
