Abstract

Provided is a thermally conductive sheet including an oriented-graphite thermally conductive layer and an insulating thermally conductive layer stacked on the oriented-graphite thermally conductive layer, the oriented-graphite thermally conductive layer including a polymer matrix including a plate-like graphite powder, flat surfaces of particles of the plate-like graphite powder being oriented in the thickness direction of the sheet, the insulating thermally conductive layer including a polymer matrix including an insulating thermally conductive filler dispersed in the polymer matrix, the insulating thermally conductive layer having a thermal conductivity and an insulating property. The thermally conductive sheet has a high thermal conductivity and an insulating property, is capable of being readily fixed to an adherend, and is easy to handle.
