PROBLEM TO BE SOLVED: To obtain the subject epoxy resin composition excellent in high temper ature storage properties, and a balance of the high temperature storage proper ties and flame retardant properties containing an epoxy resin, a phenolic resin, an activated carbon, an inorganic filler, a hardening accelerator, diantimony tetraoxide and/or diantimony pentaoxide and a brominated epoxy resin as indispensable components. SOLUTION: This epoxy resin composition contains (A) an epoxy resin (e.g.; an ortho-cresol novola type epoxy resin), (B) a phenolic resin (e.g.; a phenolic novola resin), (C) 0.1-5 wt.% activated carbon based on the total composition, (D) an inorganic filler, (E) a hardening accelerator, (F) 0.1-5 wt.% diantimony tetraoxide and/or diantimony pentaoxide based on the total composition and (G) preferably 0.1-3 wt.%, as an amount of bromine based on the total composition, brominated epoxy resin as indispensable components. The component (C) preferably has 10-100μm mean particle diameter and 800-3,500 m2/g specific surface area measured by BET method.
