PROBLEM TO BE SOLVED: To provide a semiconductor-sealing epoxy resin composition excellent in high temperature storage properties and moisture-proof reliability as well as in the balance thereof with flame retardancy. SOLUTION: This resin composition comprises, as essential components, an epoxy resin, a phenol resin, 0.1-5 wt.%, based on the total resin composition, of a red phosphorus-based flame-retardant obtained by coating the surface of red phosphorus with aluminum hydroxide and subsequently coating the surface thereof further with a phenol resin, 1-10 wt.%, based on the total resin composition, of a fused spherical silica coated with zinc molybdate or tale coated with zinc molybdate, an inorganic filler and a curing accelerator.
