A method for manufacturing a wiring board including: providing a laminate including an insulating material layer and a copper layer provided on a surface of the insulating material layer, and in which the copper layer is an electroless copper plating layer; forming a resist pattern including a groove reaching a surface of the copper layer on the surface of the copper layer; and filling the groove with a conductive material containing copper by electrolytic copper plating. The thickness of the electroless copper plating layer is, for example, 20 nm to 200 nm.
