Abstract:
Producing a circuit board, by laminating, on a substrate, an adhesive film with a metal film, which comprises a water-soluble polymer release layer, a metal film layer and a curable resin composition layer, which are formed in this order on a support layer, and has a release property enabling detachment of said water-soluble polymer release layer from the support layer after curing of the curable resin composition layer, such that the curable resin composition layer contacts the substrate; curing the curable resin composition layer; detaching the support layer, and removing the water-soluble polymer release layer present on the metal film layer by dissolving the release layer in an aqueous solution, efficiently forms an insulating layer and a metal film layer superior in adhesiveness to the insulating layer and in uniformity.
