PROBLEM TO BE SOLVED: To provide an epoxy resin composition that has excellent electric properties, for example, high dielectric constant as well as dielectric dissipation factor and can give small-sized electronic parts relatively simply by improving the coating properties of the epoxy resin composition. SOLUTION: The high dielectric constant powder of which surfaces are coated with a cyanoethylated resin is added in an amount of 30-70 vol.% to 70-30 vol.% of an epoxy resin (including the curing agent and the curing accelerator) to prepare the high dielectric constant epoxy resin. In this case, the cyanoethylated resin is selected from cyanoethylated pullulan, cyanoethylated starch and cyanoethylated polyol resin. COPYRIGHT: (C)2005,JPO&NCIPI
