METHOD FOR MANUFACTURING HEAT-CONDUCTING MATERIAL, HEAT-CONDUCTING MATERIAL, HEAT-CONDUCTING SHEET, AND DEVICE PROVIDED WITH HEAT-CONDUCTING LAYER

摘要

The present invention provides a method for manufacturing a heat-conducting material, whereby a heat-conducting material having exceptional thermal conductivity can be obtained, using a heat-conducting-material-forming composition that has a reduced filler content. The present invention also provides a heat-conducting material, a heat-conducting sheet, and a device provided with a heat-conducting layer.　This method for manufacturing a heat-conducting material comprises using a heat-conducting-material-forming composition including an epoxy compound and a phenol compound that includes a compound represented by general formula (P0), the ratio of the number of epoxy groups to the number of phenolic hydroxyl groups being 40/60 to 60/40, and the composition not including a filler, or the filler content being 10 mass% or less with respect to the total solid content when the composition includes a filler, wherein the method includes a pre-curing step and a main curing step.
