A liquid epoxy resin composition comprising a liquid epoxy resin, a curing agent, and an inorganic filler is useful for semiconductor encapsulation when the curing agent contains 5-100% by weight of a specific aromatic amine compound of at least 99% pure, the epoxy resin and the curing agent are present in a molar ratio from 0.7 to 0.9, and the composition has a toughness K1c of at least 3.5. The composition is adherent to the surface of silicon chips, does not deteriorate under hot humid conditions, and is fully resistant to thermal shocks.
