Abstract

An epoxy resin composition for sealing semiconductor elements comprising o-cresol-novolak type epoxy resins, curing agents, curing accelerators, inorganic fillers, plasticizers and imide-epoxy resins having the formula (I) is disclosed. Use of the imide-epoxy resin in an amount of 0.1 to 20.0% by weight improves the heat and moisture resistant properties of the epoxy resin composition. ##STR1## wherein, R.sub.1 and R.sub.2 denote independently H or (CH.sub.2)nCH.sub.3 radical, PA1 n denotes 0 or an integer of 1 above.
