Title:
グラファイト複合フィルム及びその製造方法
Document Type and Number:
Japanese Patent JP7022900
Kind Code:
B2
Abstract:
Provided is a graphite composite film that is capable of attaining both a measure against heat and a measure against electromagnetic noise and that has excellent high-frequency electromagnetic wave shielding performance. The graphite composite film is configured to include a graphite layer, a first electrically conductive adhesive layer, a first metal layer containing a first metal, and a second metal layer containing a second metal disposed in this order. With an arithmetic average roughness of a surface on a first electrically conductive adhesive layer-disposed side of the first metal layer defined as Ra1 and an arithmetic average roughness of a surface of the second metal layer opposite from a surface on a first metal layer-disposed side of the second metal layer defined as Ra2, at least one of the Ra1 or the Ra2 is less than or equal to 50 nm.
