METHOD FOR PRODUCING THERMAL CONDUCTIVE SHEET

摘要

A thermal conductive sheet of which the porosity is sufficiently reduced and which exhibits excellent flexibility and thermal conductivity in the plane direction. Said thermal conductive sheet is produced by employing a method which involves: preparing a starting material component (27) containing plate-like boron nitride particles (23) and a polymer matrix (24); forming a long sheet (20) from the starting material component (27) by means of a calender (1); and pressing the long sheet (20). As a consequence, the thermal conductive sheet is produced with excellent production efficiency while effectively preventing the plate-like boron nitride particles (23) from being crushed.
