Abstract

A novel fine carbon fiber produced by vapor growth, in which a graphite-net plane consisting of carbon atoms alone forms a temple-bell-shaped structural unit including a closed head-top part and a body-part with an open lower-end, in which an angle θ formed by a generatrix of the body-part and a fiber axis is less than 15°, 2 to 30 of the temple-bell-shaped structural units are stacked sharing a central axis to form an aggregate, and the aggregates are connected head-to-tail with a distance to form a fiber. Fine short carbon fibers with excellent dispersibility can be obtained by shortening the fine carbon fiber.
