PROBLEM TO BE SOLVED: To prepare a resin composition where the variation in surface electric resistance is stably controlled so as to exist in a specific range by including a specific poly(ether/aromatic ketone) and specific carbon fibers in a specific content ratio. SOLUTION: This resin composition is prepared by including (A) 90-60 wt.% poly(ether/aromatic ketone) having repeating units of the formula and (B) 10-40 wt.% carbon fibers subjected to electric resistance augmentation treatment, and having 3-25μm average fiber diameter and 50-70,000μm average fiber length. When the resin composition is molded into a molded article, the variation in the surface electric resistance of the molded article preferably is controlled stably so as to exist between 106Ωand 1012Ω. The ingredient B preferably has 10-2Ω-103Ωvolume resistivity value, which enables trouble due to short circuit to be prevented, enables the adhesion of dust or the like in use to sufficiently be controlled and enables the resin composition to be widely used in the field where antistaticity is required.
