Estimating the term…
A thermal conductivity sheet is provided which is superior all in heat radiating characteristics (thermal conductivity) in the direction of sheet thickness, close-contact with respect to parts to be cooled, and electrical insulation. In a thermal conductivity sheet 1 in which a plurality of highly thermally conductive insulators 3 are dispersed in a matrix insulator 2, the highly thermally conductive insulators 3 are oriented obliquely or erectly in the direction of thickness of the thermal conductivity sheet 1 such that at least one end faces of the highly thermally conductive insulators 3 are exposed to a surface of the matrix insulator 2. Preferably, a ratio of the total sectional area of the highly thermally conductive insulators 3 to the total surface area of the thermal conductivity sheet 1 is set to be equal to or larger than 1%.
A thermal conductivity sheet in which a plurality of thermally conductive insulators, each insulator having two end faces, and are continuously interconnected through a flexible matrix insulator, wherein only a portion of said thermally conductive insulators are arranged obliquely in the direction of thickness of said thermal conductivity sheet such that at least one end face of each of said thermally conductive insulators in said portion of insulators arranged obliquely is exposed to a surface of said matrix insulator.
