PROBLEM TO BE SOLVED: To provide a conductive polyamide resin composition which comprises a polyamide resin and carbon black, has a specified composition and a specific morphology structure, and can provide molded articles having conductivity, high impact strength, and excellent sliding characteristics. SOLUTION: A conductive 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), wherein the polyamide resin (A) forms a continuous phase; the ethylene/α-olefin copolymer (C) is dispersed in the continuous phase of the polyamide resin (A) as particles having an average particle size of not more than 2μm; and not less than 80% by mass of the conductive carbon black (B) is dispersed in the continuous phase of the polyamide resin (A).
