Method for manufacturing carbonaceous film and method for manufacturing graphite film

A method for manufacturing a carbonaceous film with use of a continuous carbonization apparatus, said method comprising the step of:

• transporting a polymeric film and/or a raw material carbonaceous film, of which the carbonaceous film is to be made, at a temperature of 550° C. to 800° C., while applying pressure to the polymeric film and/or the raw material carbonaceous film in a film thickness direction, so that the pressure causes a friction on the polymeric film and/or the raw material carbonaceous film, wherein
• the raw material carbonaceous film has been obtained by heat-treating the polymeric film,
• the polymeric film and/or the raw material carbonaceous film is pressured in a planar manner,
• the pressure applied to the polymeric film and/or the raw material carbonaceous film in the film thickness direction is 1 g/cm2 or higher and 20 g/cm2 or lower,
• i) a transporting force for said transporting the polymeric film and/or the raw material carbonaceous film and ii) a pulling force are applied to the polymeric film and/or the raw material carbonaceous film,
• the transporting force is applied to the polymeric film and/or the raw material carbonaceous film in a direction in which the polymeric film and/or the raw material carbonaceous film is transported, and
• the pulling force is 5 kgf/cm2 or higher and 200 kgf/cm2 or lower, and is applied to the polymeric film and/or the raw material carbonaceous film in a direction opposite to the direction in which the transporting force is applied.
