ABSTRACT:
The present invention is to provide a conductive masterbatch using a polyamide resin, the conductive masterbatch that has an excellent kneadability/manufacturability and formability and an excellent dispersibility of conductive fillers such as a carbon black, and shows stable conductivity even when a large amount of such conductive fillers are contained therein, and a resin composition containing the conductive masterbatch. That is, the present invention is to provide the conductive masterbatch, which includes at least a conductive filler selected from carbon blacks and carbon nanotubes, a polyamide resin, and a copolymer which contains at least a vinyl monomer having a functional group reactive with the polyamide resin and a styrene as monomer units, and in which the content of the conductive filler is in the range of 10% by mass to 40% by mass, and the resin composition containing the conductive masterbatch.
