ABSTRACT:
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 102to 1010Ω. 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.
