Zusammenfassung:	An epoxy resin-impregnated glass cloth sheet having an adhesive layer provided on at least one side of the surface thereof, characterized in that (A) said epoxy resin-impregnated glass cloth sheet is formed by impregnating glass cloth with a curable epoxy resin composition and curing it, said curable epoxy resin composition comprising an epoxy resin represented by the following structural formula (I), a brominated epoxy resin and a curing agent for epoxy resin in such an amount that the content of the epoxy resin represented by the following structural formula (I) is 5 to 50% by weight based on the amount of the entire epoxy resins and the content of bromine atom is 14 to 30% by weight based on the combined amount of the entire epoxy resins and the curing agent for epoxy resin; and (B) said adhesive layer is composed of a curable epoxy resin composition comprising an epoxy resin represented by the following structural formula (I), a brominated epoxy resin, an acrylonitrile/butadiene copolymer having carboxyl groups in its molecule which is a solid at room temperature, and a curing agent for epoxy resin in such an amount that the content of the epoxy resin represented by the following structural formula (I) is 5 to 70% by weight based on the amount of the entire epoxy resins, the content of the acrylonitrile/butadiene copolymer is 20 to 70 parts by weight based on 100 parts by weight of the entire epoxy resins and the content of bromine atom is 10 to 30% by weight based on the combined amount of the entire epoxy resins, the acrylonitrile/butadiene copolymer and the curing agent for epoxy resin. u
