ABSTRACT:
This invention provides a thermosetting resin compound containing 25% or more by volume of anisotropic structure in the resin ingredient, wherein a structure constituting said anisotropic structure has a covalent bond and the maximum diameter of the structure is 400 nm or more. The resin ingredient of said thermosetting resin compound is preferably a hardened epoxy resin compound containing a mesogen-structured epoxy resin monomer and an epoxy resin hardening agent. The epoxy resin monomer in the thermosetting resin compound is preferably an epoxy resin monomer expressed by the following formula: E-M-S-M-E, wherein E, M, and S respectively indicate an epoxy group, a mesogen group, and a spacer. Therefore, this invention can provide a highly thermal conductive hardened thermosetting resin compound whose thermal conductivity is increased highly.
