    Abstract: PROBLEM TO BE SOLVED: To improve productivity of a circuit board by increasing the absorptivity of laser light of a resin film, in a method for manufacturing the circuit board including a step of forming a circuit pattern by irradiating the resin film formed on an insulating substrate surface with laser light.SOLUTION: This resin composition includes: a copolymer composed of a monomer containing a monomer unit having at least one carboxyl group and a monomer capable of copolymerizing with this monomer; and an ultraviolet absorber. In the resin composition, when the absorption coefficient per unit weight of the resin film 2 is ε1 in a solution in which the resin film 2 that is created by applying resin liquid of the resin composition is dissolved by a solvent, ε1 at a wavelength of light with which the resin film 2 is irradiated is 0.01 (L/(g.cm)) or more.
