Abstract
An electroconductive composite plastic sheet comprising a substrate sheet made of at least one thermoplastic resin selected from the group consisting of a polyphenylene ether type resin, a polystyrene type resin and an ABS type resin and having laminated on each side of the substrate sheet, an electroconductive resin composition comprising (A) at least one thermoplastic resin selected from the group consisting of a polyphenylene ether type resin, a polystyrene type resin and an ABS type resin, (B) carbon black, and (C) an olefin type resin or (C1) a resin obtained by hydrogenation of a styrene/diene block copolymer, said electroconductive resin composition containing from 5 to 50 parts by weight of (B) the carbon black per 100 parts by weight of (A) the thermoplastic resin, and from 1 to 30 parts by weight of (C) the olefin type resin or (C1) the resin obtained by hydrogenation of a styrene/diene block copolymer, per 100 parts by weight of the total amount of (A) the thermoplastic resin and (B) the carbon black, and the sheet having the electroconductive resin composition laminated on each side thereof having a surface resistivity of from 10.sup.2 to 10.sup.10 .OMEGA..
