Abstract
A curable resin composition layer (3) containing an insulating resin and a curing agent is formed on the surface of an inner layer board having an electrical insulating layer (1) with a conductor circuit (2) formed on the surface, so as to cover said conductor circuit. A compound (4) having a structure capable of coordinating to metal atoms or metal ions is brought into contact with the surface of the curable resin composition layer. An electrical insulating layer (7) is formed by curing the curable resin composition layer. A metallic thin film layer (8) is formed on the surface of the electrical insulating layer. A conductor circuit (9) is formed on the surface of the electrical insulating layer utilizing the metallic thin film layer. A multilayer circuit board is manufactured through these steps.
