PROBLEM TO BE SOLVED: To provide a graphite film which is more excellent in tensile strength in the film surface direction or/and peel strength in the film thickness direction, and thermal conductivity than heretofore. SOLUTION: The graphite film has tensile strength in the film surface direction of ≥50 MPa and/or an interlaminar peel strength at 90° peel in the film thickness direction of ≥0.08 N/5 mm and/or thermal conductivity in the surface direction of ≥400 W/(m×K). Thereby, the graphite film has excellent tensile strength in the film surface direction, interlaminar peel strength in the film thickness direction, and thermal conductivity.
