Claim:
1. A resin composition comprising: (A) 65 to 85 parts by weight of an aromatic polycarbonate resin (component A); (B) 15 to 35 parts by weight of graphite having an average particle diameter of 5 to 60 μm and having an average ratio of length in a longitudinal direction to thickness of 30 to 68 (component B); and (C) 0.1 to 5 parts by weight of at least one compound (component C) selected from the group consisting of a polyester having a sulfonate group (component C-1) and a polyether ester having a sulfonate group (component C-2) based on 100 parts by weight of the total of the components A and B, wherein the component C-1 is a polyester comprising: (C1-1) a recurring unit derived from an aromatic dicarboxylic acid component having no sulfonate group, (C1-2) a recurring unit derived from an aromatic dicarboxylic acid component substituted by a sulfonate group and represented by the following general formula [1], and (C1-3) a recurring unit derived from a glycol component having 2 to 10 carbon atoms, and wherein the component C-2 is a polyether ester comprising: (C2-1) a recurring unit derived from an aromatic dicarboxylic acid component having no sulfonate group, (C2-2) a recurring unit derived from an aromatic dicarboxylic acid component substituted by a sulfonate group and represented by the following general formula [1], (C2-3) a recurring unit derived from a glycol component having 2 to 10 carbon atoms, and (C2-4) a recurring unit derived from a poly(alkylene oxide)glycol component having a number average molecular weight of 200 to 50,000, wherein Ar is a trivalent aromatic group having 6 to 20 carbon atoms, and M + is a metal ion or an organic onium ion.
