Abstract

The purpose of the present invention is to provide a heat release sheet and a heat sink that have excellent heat conductivity to both of plane direction and orthogonalized direction and can efficiently release heat which generates from a notebook computer and a plasma television etc. The heat release sheet is comprised of an expansive graphite sheet and a reticulated body, wherein said reticulated body is comprised of metal wire, and it is overlapped on both sides of said expansive graphite sheet, and said expansive graphite sheet and said reticulated body are combined by metal rolling process. The heat sink is comprised by forming the heat release sheet.
