PURPOSE: An electrically-conductive resin composition having improved direct electric plating properties, and plate adhesion, obtained by blending a polyolefin resin with carbon black, sulfur, and trithiolcyanuric acid in a specific ratio.

CONSTITUTION: (A)100pts.wt. polyolefin resin[e.g., propylene homo polymer, etc. (preferably one havng a MI value of ≥20)is blended with (B) 10W60pts.wt. carbon black (preferably electrically-conductive carbon black), (C) 0.1W6pts.wt., preferably 0.3W5pts.wt. sulfur, (D) 0.1W5pts.wt., preferably 0.3W2pts.wt. trithiolcyanuric acid, and, if necessary, an inhibitor for deterioration of metal, etc. by a single screw extruder, etc. preferably in a low-temperature range, to give the desired resin composition. The resin composition can be molded into the given molded article by molding process such as injection molding, etc.
