PURPOSE: An electrically conductive resin composition having high electrical conductivity, improved flexibility and high mechanical strength, obtained by blending a polyolefin resin with a fixed amount of elastomer to give a resin composition and adding a fixed amount of electrically conductive filler to the resin composition.

CONSTITUTION: (a) 100pts.wt. resin composition obtained by blending (i) 100pts. wt. polyolefin resin (e.g. polypropylele, etc.) with (ii) 20W100pts.wt. elastomer (e.g. styrene olefin copolymer, etc.) is incorporated with (B) 10W100pts.wt. electrically conductive filler (e.g. carbon black, graphite, etc.) to give the aimed composition.
