The epoxy resin composition contains an epoxy resin, a hardener, alumina particles, and a silane compound. The silane compound does not have a functional group that reacts with an epoxy group, and has a functional group that does not react with an epoxy group. It also has a structure in which the functional group that does not react with the epoxy group is bonded to a silicon atom or a chain hydrocarbon group having 1 to 5 carbon atoms is bonded to the silicon atom. |
