To provide a semiconductor carbon film, and a semiconductor device that may be easily manufactured at low cost and whose band gap may be easily controlled, and a method of manufacturing the semiconductor carbon film.

The semiconductor carbon film consists of polycyclic carbon having bond and containing at least any of five-membered ring, six-membered ring, and seven-membered ring; and hydrogen and/or nitrogen bonded to the polycyclic carbon. When the polycyclic carbon is assumed as 100 pts.wt, the amount of hydrogen and/or nitrogen is 5 to 20 pts.wt.
