PROBLEM TO BE SOLVED: To provide a conductive polybutylene terephthalate resin composition which has high stiffness and conductivity and exhibits excellent size properties and surface smoothness excellent in product appearance. SOLUTION: The conductive polybutylene terephthalate resin composition is composed of formulation of 1-30 pts.wt. of (C) a conductive carbon black and 1-100 pts.wt. of (D) a fibrous inorganic reinforcing material to 100 pts.wt. of (A)+(B) composed of formulation of 1-40 wt.% of (B) an epoxy group-containing vinyl-based copolymer to 60-99 wt.% of (A) a polybutylene terephthalate resin (the sum of (A)+(B) is 100 wt.%). The epoxy group-containing vinyl-based copolymer has, as its constitutional units, (b-1) a vinyl cyanide monomer, (b-2) an aromatic vinyl monomer, and (b-3) an epoxy group-containing vinyl monomer.
