    • Disclosed herein is a method for producing a roll-shaped carbonaceous film by polymer pyrolyzis while suppressing the occurrence of fusion bonding in the roll-shaped carbonaceous film. The carbonaceous film production method includes the step of heat-treating a polymer film wound into a roll, wherein, at a temperature equal to or higher than the pyrolyzis onset temperature of the polymer film but equal to or lower than a temperature at which the weight of the polymer film is reduced by 40% as compared to that before heat treatment, the roll-shaped polymer film has (2-1) a gap between layers of the polymer film so that a value determined for the whole roll-shaped polymer film by dividing the thickness of the gap between adjacent layers of the polymer film (Ts) by the thickness of the polymer film (Tf) (Ts/Tf) satisfies a relationship of 0.33≦Ts/Tf≦1.50 and/or (2-2) a space inside a 50% cross-sectional circle of the roll-shaped polymer film so that the area of the space inside the 50% cross-sectional circle is 25% or more of the cross-sectional area of the 50% cross-sectional circle.

    • In a method for producing a carbonaceous film in which a polymer film is wrapped around a core and is subjected to a heat treatment, material film surfaces during the carbonization step are prevented from fusion, whereby a long carbonaceous having a large area film is obtained.Fusion can be prevented by subjecting a polymer film to a heat treatment under a reduced pressure, and under a reduced pressure while allowing an inert gas to flow. The range of the pressure reduction is preferably −0.08 MPa to −0.01 kPa. It is preferred to carry out carbonization with the pressure reduced in the range of from −0.08 MPa to −0.01 kPa while allowing an inert gas to flow. In addition, the polymer film wrapped around the core is placed in an outer casing, and provided that a value derived by dividing (internal diameter of the outer casing−diameter of the core) by 2 is designated as “a” (mm), and a thickness of wrapping of the polymer film is designated as “b” (mm), a value (b/a) derived by dividing the “b” by the “a” is set to fall within the range of from 0.2 to 0.9.

    • Disclosed herein is a production method capable of efficiently producing a carbonized film wound into a roll without the occurrence of fusion bonding between the layers of the film. The method includes a carbonization step in which a polymer film wound around a core is placed in a heating furnace and carbonized by heat treatment to obtain a carbonized film wound around the core. The carbonization step is performed by increasing a temperature of the heat treatment from an initial temperature through a pyrolysis onset temperature to a pyrolysis end temperature. In the carbonization step, the heating furnace is decompressed when the temperature of the heat treatment is lower than the pyrolysis onset temperature, and after the temperature of the heat treatment reaches the pyrolysis onset temperature, the heating furnace is not decompressed or the heating furnace is decompressed so that an absolute pressure in the heating furnace is in a range of 21.3 kPa to 101.29 kPa.

    • 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.
