Title:
THERMALLY CONDUCTIVE SHEET AND METHOD FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2020/202908
Kind Code:
A1
Abstract:
Provided is a thermally conductive sheet, etc., that is both flexible and lightweight while retaining high thermal conductivity. A method for manufacturing the thermally conductive sheet 100 comprises a step for preparing a laminate 10 in which wet-laid graphite heat-dissipating sheet layers 1 and flexible adhesive layers 2 are layered in alternation, and a step for cutting the laminate 10 to a prescribed thickness in the layering direction. The thermally conductive sheet 100 obtained in the cutting step has a thermal conductivity of 4 W/m·K or greater in a direction intersecting the layering direction of the graphite heat-dissipating sheet layers 1 and the laminate 10, and a density of 0.2 g/cm3 to 1.0 g/cm3.
