▎ 摘  要

NOVELTY - A thermally conductive film (10) is formed by arranging a binder (200) and scale-like carbon materials (100) formed by graphene layers such that the adjacent scale-like carbon materials contact each other and the major axis of the scale-like carbon materials is oriented in the surface direction of the film, and making at least portion of the minor axis of the binder and the minor axes of spaces formed by the scale-like carbon materials and the binder smaller than the minor axis of the scale-like carbon materials. USE - Thermally conductive film used in heat dissipation structure (claimed) between semiconductor element and heat sink. Uses include but are not limited to personal computers, LED light sources, thin displays, semiconductor devices, secondary batteries, automobile headlights, smartphone, digital camera, insulated gate bipolar transistor, vehicle-mounted electronic control units (ECU), etc. ADVANTAGE - The thermally conductive film ensures selective improvement of thermal conductivity in the surface direction of the film. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for heat dissipation structure, which comprises a heat source and the thermally conductive film arranged in contact with the heat source. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic cross-sectional view of thermally conductive film. 10Thermally conductive film 100Scale-like carbon materials 200Binder
