| 摘要 |
A heat conductive sheet comprising organic matrix and heat conductive filler contained in the organic matrix at a volume percent between 30% and 80%. The heat conductive filler comprises spherical shaped alumina grains which have an average grain diameter in a range between 50 mu m and 80 mu m. The heat conductive filler includes micro grains having a grain diameter of 30 mu m or less at a proportion of 5 volume,% or less with respect to the total amount of the spherical shaped alumina grains. |
