ABSTRACT:
A method of forming a multilayered wiring board having a multilayered wiring structure includes the steps of forming a first mesh wiring layer having a plurality of holes therein, and forming a second wiring layer having a plurality of wirings undulating up and down so as to descend into the holes formed in the first wiring layer. In another method, the first wiring layer is formed with a plurality of protrusions and the wirings of the second wiring layer are formed between the protrusions. In the wiring boards formed according to the methods of the present invention, crosstalk between the wirings is suppressed.
