PURPOSE: A curable resin composition is provided to form a coating film with excellent heat resistance, adhesion to a substrate, and chemical resistance. CONSTITUTION: A curable resin composition comprises a copolymer which comprises a structure unit derived from an unsaturated carboxylic acid, C2-4 cyclic ether structure, and a structure unit derived from a monomer with an ethylenically unsaturated bond; and a resin which comprises a structure unit derived from an unsaturated carboxylic acid and/or unsaturated carboxylic anhydride and a structure unit derived from a copolymerizable monomer copolymerizable with one or more selected from unsaturated carboxylic acid and unsaturated carboxylic anhydride. The acid value of the resin is 30-240 mg-KOH/g. The content of the copolymer is 40-90 weight% based on the total weight of the copolymer.
