    Abstract: A filter is disposed on a base board. The filter includes a first portion, a second portion, a ground portion, a first coupling portion and a second coupling portion. The first portion is disposed on a first layer in the base board to input signals. The second portion is disposed on the first layer to output signals. The ground portion is disposed on a second layer in the base board. The first coupling portion is disposed on the first layer. The first coupling portion is electrically coupled to the first portion and the second portion. The first coupling portion is electrically coupled to the ground portion through via holes. The second coupling portion is disposed on the first layer. The second coupling portion is electrically coupled to the first portion and the second portion. The second coupling portion is electrically coupled to the ground portion through the via holes.

    Abstract: The object of the present invention is to provide a multi-layer wiring board which is easy to adjust the characteristic impedance and is able to adapt to the narrow-pitch tendency of terminals, and a process for manufacturing the same.The present invention attain the object by providing a multi-layer wiring board, in which more than one wiring layers are stacked on a substrate with an insulating layer between them, wherein a wire formed in the wiring layer has a double layered structure consists of a first layer and a second layer, and said first layer is made of a first conductive material and said second layer is made of a second conductive material having relative magnetic permeability larger than that of the first conductive material, thereby the characteristic impedance of said wire is adjusted to a value closer to 50 ohm than that of a wire which has the same thickness as of said wire having the double layered structure, and is made of said first conductive material only, and a process for manufacturing the same.
