Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a polycarbonate resin composition for molding that contains a carbon material, has good conductivity in injection molding with a small amount of the carbon material and hardly loses the conductivity even under an injection condition of high injection speed.SOLUTION: A conductive polycarbonate resin composition includes a polycarbonate (A), a carbon nanotube (B) and an ester compound (C). The ester compound (C) is obtained by reacting dipentaerythritol (D) with a monocarboxylic acid (E) or an acid anhydride thereof. The ester compound (C) has a hydroxyl value of 100 KOH mg/g or higher and an alkali metal content in the range of 10-200 ppm.
