A liquid epoxy resin composition comprising (A) a liquid epoxy resin, (B) a curing agent, (C) a curing accelerator, and (D) an inorganic filler is provided, the curing agent (B) comprising 5 to 75 parts by weight of a mixture of 3,4-dimethyl-6-(2-methyl-1-propenyl)-1,2,3,6-tetrahydrophthalic acid and 1-isopropyl-4-methyl-bicyclo[2.2.2]oct-5-ene-2,3-dicarboxylic acid per 100 parts by weight of the entire curing agent. The composition is adherent to the surface of silicon chips, and especially to polyimide resins and nitride films and has high thermal shock resistance. A semiconductor device sealed with the cured epoxy resin composition remains reliable.
