Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a curing agent used for an epoxy resin, which is excellent in water dispersibility, excellent in emulsion stability, storage stability, and drying properties after coating for the epoxy resin, and further capable of giving a cured product excellent in strength of a coating film and corrosion resistance; an epoxy resin composition containing the curing agent; and a cured product which has water resistance and alkali resistance and is excellent in strength of a coating film and corrosion resistance.SOLUTION: The amine-based curing agent comprises an aromatic diamine adduct of an epoxy resin having an alkyl (polyoxyalkylene) group in a side chain which is obtained by the reaction of: a modified epoxy resin obtained by the reaction of an epoxy resin having at least two epoxy groups in one molecule and an alkyl(polyoxyalkylene) amine compound; and an aromatic diamine.
