Title: HEAT CONDUCTIVE INSULATING SHEET AND METHOD FOR PRODUCING SAME
Abstract:
The purpose of the present invention is to provide a heat conductive insulating sheet which has achieved a good balance between insulating properties and heat conductivity higher than ever before. A heat conductive insulating sheet according to the present invention contains a heat conductive spherical filler (excluding boron nitride), a boron nitride filler and a binder resin, and has a plurality of layers (A) that mainly contain the heat conductive spherical filler (excluding boron nitride) and one or more layers (B) that mainly contain the boron nitride filler, with the layers (A) and the layers (B) being alternately laminated so that layers (A) form the outermost layers.
