Beschreibung
Zusammenfassung:	Provided is an interlayer insulating material that can enhance the adhesion between an insulating layer and a metal layer, and can reduce the surface roughness on a surface of the insulating layer. The present invention is an interlayer insulating material used for a multilayer printed wiring board, which contains an epoxy compound, a curing agent, a silica, and a polyimide, and in which the polymide is a reactant of a tetracarboxylic anhydride and a dimer acid diamine, a content of the silica is 30% by weight or more and 90% by weight or less in 100% by weight of components excluding a solvent in the interlayer insulating material, and the total content of the epoxy compound and the curing agent in 100% by weight of components excluding the silica and a solvent in the interlayer insulating material is 65% by weight or more.
