    Abstract: PROBLEM TO BE SOLVED: To provide a method of manufacturing a wiring substrate by which high-density wiring can be formed with high accuracy without using a plated resist.
    SOLUTION: The method is used to manufacture a wiring substrate by a nonelectrolytic plating method which can precipitate metal without using the plated resist, and it includes a step (a) to form a catalyst layer in a specified pattern on a substrate, a step (b) to form a first metal layer by immersing the substrate in a nonelectrolytic plating liquid to precipitate metal on the catalyst layer, a step (c) to expose the upper surface of the substrate in steam, and a step (d) to form a second metal layer by immersing the substrate in the nonelectrolytic plating liquid to further precipitate metal on the first metal layer.

    Abstract: PROBLEM TO BE SOLVED: To cause an unevenness not to be formed in the passing direction of the electric signal of a wiring, and to increase a surface area in section without changing the distance of the wiring, whereby an insulating board is adhered to a first conductive layer with no clearance to enhance an adhering force. SOLUTION: The wiring board is formed with a first conductive layer 7 and a second conductive layer 9 on an insulating board 1. In the section of a boundary between the first conductive layer 7 and the second conductive layer 9, at least the surface of the first conductive layer 7 is smaller than a side coming into contact with the insulating board 1, and a third conductive layer 11 is formed so as to coat surfaces of the first and second conductive layers.
