A flame retardant epoxy resin composition is consisted of epoxy resin (A), hardener (B), and phosphorus-containing flame retardant polyester resin (C). The phosphorus-containing flame retardant polyester resin (C) is formed from the reactive phosphorus-containing component (s) as shown in formula (I) through condensation reaction or polycondensation reaction. The flame retardant epoxy resin composition includes a phosphorus-containing flame retardant polyester resin (C), which contained no halogen. So the generating of toxic gas can be prevented when the composition is burned. And the forming property of the composition is good. The hardened substance of the epoxy resin composition has good heat resistance, water tolerance, chemical resistance, flame retardant, solder resistance property, wet fastness, and tracking resistance property.
