The present invention relates to a flame retardant epoxy resin composite, which is characterized by that it contains (A) at least one kind of epoxy resin and (B) heterocyclic compound containing phosphorus and nitrogen, and said compound possesses the group capable of reacting with epoxy radical being in epoxy resin, and can be used as solidifying agent of epoxy resin. Said epoxy resin composite formed from said components of (A) and (B) possesses improved flame retardant property, suitable for flame retardant material, can be used for making composite material, laminated board, printed circuit board and electronic and electric products. Besides, the solidifying agent containing no phosphorus, solidification accelerant and other additives of solvent, etc. can be selectively added.
