PROBLEM TO BE SOLVED: To provide a polyamide-based conductive resin composition capable of laser marking. SOLUTION: The polyamide-based conductive resin composition capable of laser marking includes: (A) 70-50 pts.mass of a polyamide resin; (B) 10-20 pts.mass of an antistatic agent; (C) 15-30 pts.mass of an ethylene-α-olefin copolymer having a reactive functional group reactive with a terminal group of the polyamide resin and/or an amide group of the main chain, (D) 0.5-3 pts.mass of a black pigment, (E) 0.5-3 pts.mass of a metal-plated organic fiber, and (F) 0.5-3 pts.mass of a carbon fiber. The blending thereof is performed so that the total of (A) to (F) is 100 pts.mass and the total of the components (E) and (F) is 3 pts.mass or less. The value of residual voltage when voltage of 5 kV is applied to one optional end of a molded product obtained by performing injection molding of the resin composition while the other optional end is grounded is 1 kV or less.
