Title:
GRAPHITE SHEET AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2022/209004
Kind Code:
A1
Abstract:
The present disclosure addresses the problem of providing a graphite sheet capable of reducing thermal contact resistance by reducing thermal contact resistance on the surface of the graphite sheet. A graphite sheet (11) is formed by a plurality of graphite layers laminated in the thickness direction. At least a part of a graphite layer that forms a layer other than the outermost layer of the graphite sheet (11) is exposed on the surface of a graphite layer that forms the outermost layer. The graphite sheet (11) has a deemed shear strength of 0.1-0.5 MPa, as measured in a depth range of 0.5-19 μm by a SAICAS method.
