摘要

The present invention provides an epoxy resin composition comprising: an epoxy resin monomer that is represented by general formula (I); a curing agent that includes a novolac resin obtained by converting a divalent phenol compound into a novolac; and an alumina filler that includes alpha-alumina. In general formula (I), R1 to R4 independently represent a hydrogen atom or an alkyl group having 1 to 3 carbon atoms.
