    • A fine carbon fiber, the main body of each fiber filament of the fiber having an outer diameter of about 1 to about 500 nm and an aspect ratio of about 10 to about 15,000 and comprising a hollow space extending along its center axis and a multi-layer sheath structure consisting of a plurality of carbon layers, the layers forming concentric rings, wherein the fiber filament has a nodular portion which is formed of outwardly protruding carbon layers or formed of a locally increased number of carbon layers. A similar fine carbon fiber, in which the fiber filament has repeatedly enlarged protruding portions and the filament diameter varies along with the length of the filament, the ratio of the diameter (d") of a fiber filament of the fiber as measured at the outwardly enlarged portions to the diameter (d) of a fiber filament of the fiber as measured at a position at which no outwardly enlarged portions is present; i.e., d"/d, being about 1.05 to about 3, is also provided.
