PROBLEM TO BE SOLVED: To obtain a polymer composition from which a final object product having satisfactory surface appearance and rigidity with at least the same level as an industrial standard can easily be molded, and which has conductivity, an electrostatic discharge nature, or static electricity antistatic properties. SOLUTION: In the polymer composition comprising a polymeric material in which carbon fibrils of 0.25-50 wt% are contained, each of the carbon fibrils has a major axis, a part of the fibrils has an aggregate shape, the major axes of the fibrils in the aggregate have a substantially identical relative orientation, and the composition has notched Izod impact strength of more than 2.67 J/cm (5 ft-Ib/in) and a volume resistivity of less than 1x1011Ω/cm.
