THERMALLY CONDUCTIVE SHEET

摘要

The disclosed thermally conductive sheet, which is excellent in both the functions of thermal conductivity and electromagnetic wave suppression attributes, is provided by causing the high packing of magnetic metal particles and thermally conductive particles of which the thermal conductivity is more favorable than that of the magnetic metal particles. The thermally conductive sheet (11), which is disposed between an electronic component (14) and a metallic radiator member (12) that radiates the heat given off by the electronic component (14), is characterized: by comprising a flexible resin containing both spherical magnetic metal particles that absorb electromagnetic waves emitted from the electronic component (14) and thermally conductive particles that have a higher thermal conductivity than the magnetic metal particles; by the average particle size of the magnetic metal particles being greater than the average particle size of the thermally conductive particles; and by the volume fraction of the magnetic metal particles in said thermally conductive sheet being at least 55 vol%.
