To provide an epoxy resin composition which provides a halogen-free and excellently retardant cured product and an improved storage stability of a half-cured product, a prepreg, a resin-attached metal foil, an adhesive sheet, and a lamination plate which are prepared using the same epoxy resin composition.
The epoxy resin composition comprises a phosphorus-containing epoxy resin obtained by reacting at least one particular organic phosphorus compound with an epoxy resin, a curing agent, and an inorganic powdery filler, wherein the phosphorus-containing epoxy resin has a phosphorus content of 0.5-4.0 wt%, and the epoxy resin composition has an inorganic powdery filler content of 20-60 wt% in the total solid component. The epoxy resin composition is used to prepare the prepreg, the resin-attached metal foil, and the adhesive sheet. The prepreg, the resin-attached metal foil, and the adhesive sheet are used to prepare the lamination plate.
