PROBLEM TO BE SOLVED: To provide a remarkably simplified method of forming a conductor circuit which does not require plating or resist by solving a problem of complicated process in a conventional method of forming a conductor circuit, and to provide a wiring board to be obtained by this method. SOLUTION: The method of forming a conductor circuit is characterized in that a layer of a silicon-containing polymer is formed on an insulation layer, the formed layer is irradiated with an ultraviolet ray or a visible light after light-shielding processing is applied to a portion where a circuit is formed, and the formed layer is allowed to contact a solution of a transition metal salt or a suspension, thereby forming a transition metal layer on the non-exposed layer.
