    摘要: An epoxy resin composition contains (A) an epoxy resin having an epoxy equivalent of at least 185 and possessing a skeleton having a structure in which two benzene rings are conjugable to each other directly or via an aliphatic unsaturated double bond, carbon atoms having an atomic orbital of SP.sup.2 type accounting for at least 50% of the carbon number, (B) a phenolic resin having a hydroxyl equivalent of at least 160, carbon atoms having an atomic orbital of Sp.sup.2 type accounting for at least 85% of the carbon number, (C) a polyimide resin in an amount of 1-20 parts by weight per 100 parts by weight of components (A) and (B) combined, and (D) 70-85% by volume of the entire composition of an inorganic filler. The composition cures into products having flame retardancy and high-temperature reliability even though it is free of bromine compounds and antimony compounds.
