Provided is an epoxy resin composition comprising:
(A) an epoxy compound represented by the general formula (1) :
wherein R1 to R9 represent each independently a hydrogen atom, an acyclic or cyclic alkyl group having 1 to 6 carbon atoms, a substituted or unsubstitued phenyl group or a halogen atom,
(B) a polyfunctional epoxy compound having a functional group number of two or more, and
(C) an epoxy curing agent containing a phenolic hydroxyl group,
wherein the proportion of the epoxy compound (A) is from 1 to 99 % by weight based on the total weight of the epoxy compounds (A) and (B), whereas the epoxy resin composition contains a pyrogenically produced silica, which has been surface modified with Hexamethyldisilazane (HMDS) and structurally modified by a ball mill.
