Abstract
According to one embodiment, there is provided a graphite nano-carbon fiber provided by using an apparatus having a reactor capable of keeping a reducing atmosphere inside thereof, a metal substrate arranged as a catalyst in the reactor, a heater heating the metal substrate, a pyrolysis gas source supplying pyrolysis gas obtained by thermally decomposing a wood material in a reducing atmosphere to the reactor, a scraper scraping carbon fibers produced on the metal substrate, a recovery container recovering the scraped carbon fibers, and an exhaust pump discharging exhaust gas from the reactor. The carbon fibers are linear carbon fibers with a diameter of 25 to 250 nm formed with layers of graphenes stacked in a longitudinal direction.
