Abstract
There is provided a graphite composite film including a graphite film and a metal layer formed on a surface of the graphite film, in which peeling-off of the metal layer from the graphite film is suppressed. More specifically, the graphite composite film includes a graphite film and a metal layer formed on at least one side of the graphite film, wherein the graphite film has a plurality of through holes formed therein, a metal layer is formed also inside the through holes so as to be connected to the metal layer formed on a surface of the graphite film, the metal layer inside the through holes is formed continuously from the one side to an opposite side of the graphite film, and a distance between outer diameters of the through holes is 0.6 mm or less and a ratio of an area of metal inside the through holes to an area of the graphite composite film is 1.4% or more.
