Disclosed is a conductive polyamide resin composition that excels not only in electroconductivity, but also in fuel resistance, particularly resistance against alcohol-containing fuel, and further excels in fluidity and moldability, and is capable of yielding a molded article with high impact resistance, the conductive polyamide resin composition including: 84 to 40% by mass of a polyamide resin (A); 5 to 30% by mass of conductive carbon black (B); 3 to 30% by mass of an ethylene-&#x3b1;-olefin copolymer (C) that has a reactive functional group capable of reacting with a terminal group of polyamide resin and/or an amido group on a principal chain of polyamide resin; and 1 to 20% by mass of a conductive polyethylene resin (D).

Conductive polyamide resin composition

The polyamide resin composition according to the present invention contains a polyamide resin (A) wherein an average carbon number of an alkylene group between amide groups is 5 or less and a polyamide resin (B) wherein an average carbon number of an alkylene group between amide groups is more than 5, wherein a ratio by mass (A)/(B) of the polyamide resin (A) to the polyamide resin (B) is from 98/2 to 40/60, and wherein, to 100 parts by mass of a total amount of the polyamide resin (A) and the polyamide resin (B), 0.5 to 20 part(s) by mass of a metal cyanide salt of a composition formula (1) (A[M(CN)]) is compounded.
