INSULATING AND HEAT-CONDUCTIVE SHEET

摘要

The present invention addresses the problem of providing a heat-conductive sheet having excellent insulation properties and thermal anisotropy and also having high heat-dissipating properties. An insulating and heat-conductive sheet characterized by comprising insulating and highly heat-conductive fibers that penetrate in the thickness direction and a binder resin, wherein the penetration density of the insulating and highly heat-conductive fibers that penetrate in the thickness direction is 6% or more, the ratio of the thermal resistivity in the thickness direction to the thermal resistivity in the planar direction is 2 or more, and the initial dielectric breakdown strength is 20 kV/mm or more.
