    • PROBLEM TO BE SOLVED: To provide a thermally conductive sheet which is excellent in a thermal conductivity and an electromagnetic wave interference suppressing effect. SOLUTION: The thermally conductive sheet comprises bond and thermally conductive filler and/or soft magnetic powder, by having the thermal conductivity and the electromagnetic wave interference suppressing effect, and by having a small contact thermal resistance to a smooth surface and an irregular surface. With respect to this sheet, it is preferable that the thermally conductive filler and/or the soft magnetic powder is obtained by blending two sorts which are different within a range where a ratio of a mean particle diameter or a ratio of a mean length concerning the thermally conductive filler and/or the soft magnetic powder is 5:1 to 2:1. It is preferable that a reduction rate (K) of the contact thermal resistance calculated from formula (I) in the figure is 65% or more. COPYRIGHT: (C)2007,JPO&INPIT
    • 要解决的问题:提供导热性和电磁波干扰抑制效果优异的导热片。 解决方案:通过具有导热性和电磁波干扰抑制效果,并且通过对平滑表面具有小的接触热阻和不规则的不规则的导热性片,包括粘合和导热填料和/或软磁性粉末 表面。 对于该片材,优选的是,通过混合两种不同的导热填料和/或软磁性粉末,该平均粒径与平均粒径的比例 导热填料和/或软磁粉末为5:1至2:1。 从图中的式(I)计算出的接触热阻的减少率(K)优选为65%以上。 版权所有(C)2007,JPO&INPIT
