Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a polyolefin resin composition having excellent long-term durability of mechanical strength in an environment subjected to the influence of oxygen, heat or light, for example, keeping excellent thermal degradation resistance, light stability and copper deterioration resistance in addition to good appearance and excellent mechanical strength and provide a method for the production of the composition and a molded article produced by molding the composition. SOLUTION: The polyolefin resin composition contains (A) 100 pts. wt. of a polyolefin resin, (B) 0.001-10 pts. wt. of carbon black satisfying the requirements (1) and (2) and (C) 0.01-100 pts. wt. of a stabilizer. Requirement (1): the volatile content of the carbon black is
