Abstract: The present invention relates to a method for producing a conductive masterbatch containing a polyamide resin and a carbonaceous filler. The present invention provides a method for producing a conductive masterbatch which can suppress an increase in resin temperature during extrusion, formation of die drips, and strand breakage and can also significantly increase the output of extruding. The method is achieved by the steps of feeding the carbonaceous filler to a molten first polyamide to melt-knead them together and then feeding a second polyamide to the resulting melt-kneaded product to further melt-knead the second polyamide, the carbonaceous filler, and the first polyamide.
