摘要：
A branched vapor-grown carbon fiber having an outer diameter of 0.5 μm or less and an aspect ratio of at least 10, the carbon fiber having a compressed specific resistance of 0.02 Ω·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 Ω·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 μm, an aspect ratio of 10–15,000, and a compressed specific resistance of 0.02 Ω·cm or less, and surface resistivity of 10,000 Ω/□ or less. An electrically conductive transparent material formed from the aforementioned electrically conductive transparent composition.
