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.
