To provide a method for producing a polyamide resin composition which can provide a molding having high conductive, impact strength and excellent sliding properties by specifying a composition and the production method, in which a conductive polyamide resin composition is obtained by blending carbon black with a polyamide resin.

The method for producing an electroconductive polyamide resin composition comprises 95-40% by mass of a polyamide resin (A), 5-30% by mass of a conductive carbon black (B), 10-40% by mass of an ethylene/α-olefin copolymer (C) having a reactive functional group which is reactive with a terminal group and/or an amide group of the main chain of the polyamide resin, and 1-10% by mass of a high-density polyethylene resin (D), in which the polyamide resin (A) and the conductive carbon black (B) are previously melted and kneaded, and then the ethylene/α-olefin copolymer (C) and the high-density polyethylene resin (D) are further melted and kneaded.
