摘要： Provided is an electrically conductive resin composition with which the characteristics inherent in a thermoplastic resin are easily retained and which exhibits more excellent electrical conductivity even if the blending amount of an electrically conductive filler is small. This electrically conductive resin composition contains a thermoplastic resin, such as a polycarbonate or a polyolefin, and an electrically conductive filler, such as a carbon nanotube. This electrically conductive resin composition further contains a dye, such as a perinone-based dye or a disazo-based dye, which is a component for improving electrical conductivity, and this electrically conductive resin composition can be obtained by kneading or molding a raw material mixture containing a thermoplastic resin, an electrically conductive filler, and a dye under a condition of a temperature equal to or higher than the melting point of the thermoplastic resin.
