An electroconductive resin composition useful for packaging an electronic device, is provided, whereby a drawback that carbon black is likely to fall off from the surface of a molded product by abrasion, has been overcome. It is an electroconductive resin composition which comprises at least one thermoplastic resin selected from the group consisting of a polyphenylene ether resin, a polystyrenic resin and an ABS resin, and carbon black and which contains a styrene/butadiene/butylene/styrene block copolymer or a mixture of such a copolymer with an olefinic resin, and has a surface resistivity of from 10<SUP>2 </SUP>to 10<SUP>10 </SUP>Omega. Contamination of IC, etc., to be caused by falling off of carbon black, etc. by abrasion when contacted with IC, etc., can be substantially reduced. |
