1. A conductive resin composition, comprising:
100 parts by weight of a base resin (A) comprising a polyester, a polyarylene ether, and an aromatic elastomer;
3 to 12 parts by weight of two or more polyfunctional reaction agents (B);
0.1 to 3 parts by weight of carbon nanotubes (C);
0.1 to 5 parts by weight of carbon nanoplates (D); and
1 to 10 parts by weight of a glass powder (E),
wherein the aromatic elastomer includes one or more selected from the group consisting of styrene-butadiene-styrene (SBS) copolymers, styrene-ethylene-butylene-styrene (SEBS) copolymers, and maleic anhydride-modified styrene-ethylene-butylene-styrene copolymers,
wherein each of the two or more polyfunctional reaction agents comprises two or more functional groups selected from the group consisting of a carboxyl group, an amine group, a hydroxyl group, a maleic acid group, and an epoxy group, and
wherein the two or more polyfunctional reaction agents comprise a polyphenylene oxide resin functionalized with a carboxylic acid, maleic acid, or maleic anhydride; and a bisphenol A type epoxy resin.
