Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a foamed epoxy resin molded article with high open cell rate, excellent in compression set. SOLUTION: The foamable epoxy resin composition (E) comprises (A) a polyepoxide, (B) a hardener for epoxy resin and (C) at least one organic hollow filler selected from a group comprising following (C1), (C2) and (C3) as essential component. The molded article (D) is obtained by forming the foamable epoxy resin composition (E). (C1): An organic hollow filler comprising a vinyl monomer having a functional group (f1) and a vinyl monomer (g3) having a cyano group as essential constituting unit of a shell. (C2): An organic hollow filler comprising a vinyl monomer having a functional group (f2) which reacts with the functional group (f1) and the vinyl monomer (g3) as essential constituting unit of a shell. (C3): An organic hollow filler comprising the vinyl monomer (g1), the vinyl monomer (g2) and the vinyl monomer (g3) as the essential constituting unit of a shell. COPYRIGHT: (C)2006,JPO&NCIPI
