Thermal conductive sheet

Abstract

A thermal conductive sheet contains a plate-like boron nitride particle. The thermal conductive sheet has a thermal conductivity in a direction perpendicular to the thickness direction of the thermal conductive sheet of 4 W/m·K or more. The thermal conductive sheet does not fall off from an adherend in the initial adhesion test ( 1 ) below: Initial adhesion test ( 1 ): The thermal conductive sheet is temporarily fixed on an adherend along the horizontal direction, and thereafter the adherend is turned over to be upside down. The maximum cutting resistance on the cutting blade at the time of cutting the thermal conductive sheet is 120 N/30 mm or less.
