THERMALLY-CONDUCTIVE ELECTRICAL CONDUCTING LAYER

WIPO Patent Application WO/2023/182329

A1

Provided is a thermally-conductive electrical conducting layer excelling in thermal conductivity in the thickness direction. The thermally-conductive electrical conducting layer (1) comprises a binder component (11) and electrically-conductive particles (12). The electrically-conductive particles (12) comprise: electrically-conductive particles A (12a) having a thermal conductivity of 20 W/mK or more and a median diameter that is larger than the thickness (T) of the thermally-conductive electrical conducting layer (1); and electrically-conductive particles B (12b) having a median diameter that is smaller than the thickness (T) of the thermally-conductive electrical conducting layer (1). The resistivity of the thermally-conductive electrical conducting layer (1) is 2.0×10-5 Ω·m or more.
