PURPOSE: To render superior the heat radiation characteristics of a sheet in the thickness-wise direction thereof by the sole use of a thermally conductive flexible fabric, or by the use of that thermally conductive flexible fabric, on the upper part of which electrical insulation members are provided, as a heat radiation sheet.
CONSTITUTION: A heat radiation sheet 1 is composed of a thermally conductive flexible fabric 2 which is made of more than two types of material selected from the group consisting of a high-strength extra thin metal line, chemical fiber and carbon fiber. If necessary, electrical insulation areas 3 are provided on the thermally conductive fabric 2. The heat radiation sheet 1 is sandwiched between electronic and electrical components and a heat sink such as a heat radiating fin, whereby heat produced by the electronic and electrical components is effectively transferred in the thickness-wise direction of the heat radiation sheet 1. This makes it possible to lead to efficient cooling by the heat sink.
