PROBLEM TO BE SOLVED: To provide a resin composition excellent in moldability for impregnating a large-scaled mold coil therewith that has a long life and can suppress resin dripping on molding and suppress generation of cracks and peeling caused by heat cycle when a large-scaled coil is molded.SOLUTION: A resin composition for impregnating a large-scaled mold coil therewith comprises a resin component and a curing agent component. The resin component (A) comprises a bisphenol A type epoxy resin, (B) a polypropylene glycol diglycidyl ether and (C) a trifunctional epoxy resin, where the content of the component (A) is 65-75 mass%, the content of the component (B) is 15-30 mass% and the content of the component (C) is 5-25 mass%, each based on 100 mass% of the total of the components (A)-(C). The curing agent component comprises (D) a diphenylamine curing agent and (E) an imidazole curing accelerator. |
