PROBLEM TO BE SOLVED: To provide an epoxy resin composition excellent in curing properties at low temperatures, mechanical strengths, moisture resistance and cured physical properties such as adhesiveness and the like, especially suitable for applications in civil engineering, coatings and adhesives. SOLUTION: The epoxy resin composition comprises a modified epoxy resin (A) comprising 100 pts.mass bisphenol type liquid epoxy resin (a), 5-100 pat.mass acetoacetylated polyhydric alcohol (b) expressed by general formula (1) and 1-50 pts.mass divalent or trivalent aliphatic alcohol glycidyl ether (c) and an amine-based curing agent (B) as essential components. In the formula, A expresses a trivalent or tetravalent aliphatic alcohol residue; m expresses 0.05-0.45 in average; n expresses 2.55-3.95 in average; [m+n] expresses 3 or 4.
