PROBLEM TO BE SOLVED: To provide a method for manufacturing a graphite film and a method for manufacturing a carbonization film, capable of suppressing wrinkles when continuously sintering a high polymer film.SOLUTION: A graphite sheet having suppressed wrinkles and ripples is obtained by installing heating spaces of two or more stages and continuously sintering the graphite sheet. Especially, when a cooling space 43 exists between the heating spaces, the graphite film having excellent flatness and high thermal diffusivity can be obtained. |
