PURPOSE:To obtain a flexible electroconductive tube suitable for electric wave shielding, etc. by mixing a vinyl chloride resin with an acrylonitrile/butadiene copolymer, a specified plasticizer and an electroconductive filler of a low volume resistivity. CONSTITUTION:30-80wt% vinyl chloride resin is mixed with 70-20wt% acrylonitrile/butadiene copolymer. 100pts.wt. obtained blend resin is mixed with 10-100pts.wt. phthalate plasticizer having an ether bond in each alkyl chain and 5-50pts.wt. electroconductive filler of a volume resistivity <=1OMEGA-cm (e.g. acetylene black or stainless fiber), and the obtained mixed molded to obtain the purpose electroconductive resin tube of a volume resistivity <=10<2>OMEGA-cm. As an example of the phthalate plasticizer, di(ethylene glycol monobutyl ether) phthalate can be cited.
