To provide a resin composition having high conductivity, thin wall moldability (a flowability at the time of molding or the like), fineness of appearance together with mechanical properties and to provide a molded article of the composition.

This thermoplastic resin composition produced by using at least carbon fiber and a thermoplastic resin, manifests 1.6-3 nm of crystal size measured in a wide angle x-ray diffraction method, and 0.03-0.08 of oxygen to carbon (O/C) ratio measured by ESCA and 3-15 μm of mean single fiber diameter.
