PROBLEM TO BE SOLVED: To provide a curable resin composition which can be cured by ultraviolet rays, has long-term reliability of electrical insulation of its cured product, can be utilized in a film-forming material (an overcoating agent) and the like due to its flexibility and small warpage by cure shrinkage, and particularly can be used in the formation of a protective film for low tack, flexible wiring circuits. SOLUTION: The curable resin composition comprises a curable resin obtained by reacting (A) a carboxy group-containing urethane resin using (a) a polyisocyanate compound, (b) a polyol compound, and (c) a dihydroxy compound having a carboxy group as raw materials with (B) a compound having both a (meth)acrylic double bond and an epoxy group, and a cured product is obtained therefrom.
