PURPOSE:The titled composition which can give a mica prepreg which is excellent in impact resistance, flexibility, adhesiveness and impregnatability and can form a coil excellent in electrical and mechanical properties, comprising an epoxy resin, an acid anhydride curing agent, an accelerator and a thermoplastic resin. CONSTITUTION:1 equivalent of a bisphenol A epoxy resin and/or a flexible epoxy resin (A) or an epoxy equivalent of 184-6,000 are mixed with 0.5-1.5mol of at least one polyanhydride (B) selected from among polyazealic polyanhydride, polyadipic polyanhydride and polysebacic polyanhydride which are intermolecular anhydrides, 20-100g, per 100g of component A, of a thermoplastic resin (C) such as polyglycol and/or polycaprolactone and 0.1-5.0g, per 100g of component A, of at least one member (D) selected from among kalibolite of triethylamine, imidazole and a BF3 complex.
