ABSTRACT:
There is provided a heat sink sheet which can secure a heat source and a heat sink such as an aluminum cooling fin to each other and is superior in heat sink performance. The heat sink sheet is achieved by adhering a pressure sensitive adhesive layer adhered to the whole or part of a surface of a silicone heat sink layer. It is desirable that the pressure sensitive adhesion layer be made of an acrylic-containing adhesive or an urethane-containing adhesive, and a heat sink filler is advantageously blended with the pressure sensitive adhesive layer.
