A fuel cell separator is produced by forming a fuel cell separator resin composition including, as essential components, (A) an epoxy resin; (B) a curing agent; (C) a curing accelerator; and (D) a carbon material, in which the content of the (D) is 50 to 85% by mass based on the total amount of the composition, in which the (D) includes high crystalline artificial graphite having an average particle size of 100 &#x3bc;m or more and less than 150 &#x3bc;m in an amount of 5 to 100% by mass based on the total amount of the (D), and in which the content of the (C) is 0.1 to 20 parts by weight per 100 parts by weight of the (B). The resin composition is excellent in electric conductivity and fluidity and contains little impurities, and can provide a fuel cell separator which is excellent in electric conductivity and dimensional accuracy, and has no fear of causing deterioration in performance of a solid electrolyte.
