PROBLEM TO BE SOLVED: To obtain a resin composition which has excellent low-temperature curability and can form coating films excellent in properties such as corrosion preventive properties, adhesion and flexibility by mixing a glycidyl-terminated epoxy compound with a curing agent. SOLUTION: An epoxy compound of formula I is used. In the formula, EP is a group having a structure derived by removing one glycidyl group from a polyglycidyl compound having two or more glycidyl groups; A is a group derived by removing the two carboxyl group from an aliphatic dicarboxylic acid having anα,β-unsaturation; G is a group having a structure derived by removing (1+n) hydroxyl groups from a polyol having two or more alcoholic hydroxyl groups; and (n) is 1-2. The aliphatic dicarboxylic acid in A is particularly desirably maleic acid. The polyol in G is desirably the one having an average molecular weight of 500-5,000 or a polyether polyol. The polyglycidyl compound in EP is desirably the one represented by formula II (wherein R1 and R2 are each H or an alkyl; and (m) is 0-10).
