PROBLEM TO BE SOLVED: To maintain good flowability by preventing deterioration in flowability while suppressing lowering of impact strengths to a minimum extent on incorporating carbon black with polypropylene to make it electroconductive. SOLUTION: The electroconductive composition comprises 30-84 wt.% of a polypropylene resin, 15-50 wt.% of carbon black, and 1-20 wt.% of at least one wax selected from among polypropylene homopolymers and copolymers of propylene with ethylene or anα-olefin, each polymerized with a metallocene catalyst, and a molded article thereof has a surface resistance within the range from 1E+01 to 1E+09Ω/sq.
