PROBLEM TO BE SOLVED: To provide carbon fibers for providing a heat radiating material with a high heat radiation performance. SOLUTION: The carbon fiber is produced by using mesophase pitch as raw material, and controlling surface condition, average fiber diameter, percentage of diameter dispersion of fiber to average fiber diameter (CV value), number average fiber length, volume average fiber length, and a composition and formed article is produced by using the fiber.
