PROBLEM TO BE SOLVED: To obtain an epoxy resin composition which has storage stability for a long time, excellent handling property, a satisfactory curing rate at a predetermined temperature and suffices excellent mechanical strength, heat resistance of a cured product, and to provide a prepreg using the same. SOLUTION: The epoxy resin composition which comprizes (A) an epoxy resin, (B) a curing agent and (C) at least one compound selected from among imidazole derivatives and urea derivatives is characterized in that it contains 0.03-0.3 wt.% of hydrolyzable chlorine and has a glass transition temperature from -10 to 15°C. A prepreg containing the resin composition and a reinforcing fiber is also provided. COPYRIGHT: (C)2004,JPO
