To provide a coating film composition which prevents the production of a metal salt and improves a metal layer corrosion-preventing effect, an ion migration-preventing effect, and adhesiveness to substrates, and to provide a method for producing the same.

This coating film composition is characterized by containing a crown compound. A polyimide-based coating film composition is characterized by comprising at least a crown ether compound, a cyclic polyamine compound, and a cyclic polythioether compound. A method for producing the polyimide-based coating film is characterized by treating the surface of a metal wiring or metal layer disposed on a substrate with a crown ether compound, a cyclic polyamine compound and a cyclic polythioether compound, coating the surface-treated substrate with a polyimide-based coating film composition, and then drying the coated substrate.
