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