THERMALLY CONDUCTIVE SHEET

摘要

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.
