Sheet for conducting heat

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 mum and 80 mum. The heat conductive filler includes micro grains having a grain diameter of 30 mum or less at a proportion of 5 volume % or less with respect to the total amount of the spherical shaped alumina grains.
