COMPOSITION FOR FORMING INSULATION LAYER, FILM FOR FORMING INSULATION LAYER AND SUBSTRATE

摘要

PROBLEM TO BE SOLVED: To provide an insulation layer forming composition and an insulation layer forming film capable of forming an insulation layer having excellent heat-conductivity and insulation properties, and to provide a substrate having excellent heat-dissipation properties and reliability.SOLUTION: There are provided an insulation layer forming composition for forming an insulation layer and constituted of a resin material, a filler composed of an inorganic material and a silane coupling agent having a secondary amino group; an insulation layer forming film having an insulation layer forming layer obtained by forming the insulation layer forming composition in the form of a layer; and a substrate having a metallic plate made of a metallic material, an insulation layer formed on the metallic layer and comprising a cured material or solidified material obtained by forming the insulation layer forming composition in the form of a layer, and a conductive layer formed on a face of the insulation layer opposite to the face having the metallic plate.
