Abstract: A thermally conductive sheet includes a binder resin and boron nitride flakes. The boron nitride flakes are oriented in a thickness direction of the thermally conductive sheet, and both surfaces of the thermally conductive sheet are tacky. A method for manufacturing a thermally conductive sheet includes preparing a thermally conductive composition containing a binder resin and boron nitride flakes. A molded block is formed from the thermally conductive composition. The molded block is sliced into a sheet shape to obtain a thermally conductive sheet precursor. The thermally conductive sheet precursor is pressed to obtain a thermally conductive sheet.

Abstract: A thermally-conductive sheet includes: a binder; and an anisotropic thermally-conductive filler. The anisotropic thermally-conductive filler is oriented in a thickness direction of the thermally-conductive sheet An arithmetical mean height Sa is 5 ?m or less and a maximum height Sz is 50 ?m or less on either surface of the thermally-conductive sheet. A dielectric breakdown voltage of the thermally-conductive sheet is 0.5 kV/mm or higher.
