Abstract
The optical/electrical composite wiring board comprises a lower insulating layer that also serves as a lower clad; a upper insulating layer that also serves as an upper clad; a core that is placed between the lower insulating layer and the upper insulating layer and has a predetermined optical wiring pattern; and a conductor layer that is placed along with the core between the lower insulating layer and the upper insulating layer and has a predetermined electrical wiring pattern. Herein, the core and the conductor layer are formed via a short manufacturing method, whereby the concave portion for optical wiring and the concave portion for electrical wiring are formed on the lower insulating layer by press process, and a core material and conductor material are filled into each of the concave portions, and afterward, the core material and conductor material are ground until they are flush with the upper surface of the lower insulating layer.
