A branched vapor-grown carbon fiber having an outer diameter of 0.5 .mu.m or less and an aspect ratio of at least 10, the carbon fiber having a compresse d specific resistance of 0.02 .OMEGA..cm or less, each fiber filament having a hollow cylindrical structure, preferably the carbon fiber containing boron a nd having a compressed specific resistance of 0.018 .OMEGA..cm or less. An electrically conductive transparent composition comprising a resin binder an d carbon fiber incorporated into the binder, having transparency and comprisin g vapor-grown carbon fiber having an outer diameter of 0.01-0.1 .mu.m, an aspe ct ratio of 10-15,000, and a compressed specific resistance of 0.02 .OMEGA..cm or less, and surface resistivity of 10,000 .OMEGA./.square. or less. An electrically conductive transparent material formed from the aforementioned electrically conductive transparent composition. |
