NOVELTY - Thermoplastic resin composition is obtained by melt-kneading at least a thermoplastic resin, a carbon nanostructure, and graphene or carbon black having a Brunauer-Emmett-Teller (BET) specific surface area of at least 400 m2/g, where the blending amount of the carbon nanostructure with respect to 100 parts by mass of the thermoplastic resin is 0.5-2 parts mass, and the total amount of the carbon nanostructure and the graphene or the carbon black is 0.5-2.5. USE - The composition is used for manufacturing a member such as conductive member (all claimed). The composition is used for producing a molded product having an antistatic function. ADVANTAGE - The composition are provided with conductivity, without significantly reducing impact resistance and tensile fracture strain, or is possible to impart conductivity without significantly reducing impact resistance and tensile fracture strain. The member has high conductivity, and has sufficient impact resistance and tensile fracture strain, and the conductive member has high conductivity and sufficient impact resistance and tensile fracture strain.
