    • Disclosed herein is a method for producing an elongated (rolled) carbonaceous film by polymer pyrolysis while suppressing the fusion bonding of the carbonaceous film. The method for producing a carbonaceous film includes the step of heat-treating a polymer film wound into a roll, wherein the heat treatment is performed after the polymer film is wound into a roll to have a gap between adjacent layers of the polymer film at a temperature lower than a pyrolysis onset temperature of the polymer film so that the roll of polymer film as a whole satisfies a relationship that a value obtained by dividing a thickness of a gap between adjacent layers of the polymer film (Ts) by a thickness of the polymer film (Tf) (Ts/Tf) is 0.16 or higher but 1.50 or lower. As a method for forming gaps between the layers of the polymer film, a method in which the polymer film is wound into a roll together with a slip sheet and then the slip sheet is removed can be used, which is effective at suppressing the fusion bonding of a carbonaceous film.
