Abstract:
1. A method for manufacturing an opto-electrical hybrid wiring board, comprising: aligning a flexible wiring board between a first rigid material and a second rigid material and forming insulation layers on both surfaces of the flexible wiring board, the first rigid material and the second rigid material; exposing part of the flexible wiring board between the first rigid material and the second rigid material; forming a via in the first or second rigid material which supports the flexible wiring board, the via penetrating a surface of the flexible wiring board and extending partially into the flexible wiring board to electrically connect the first or second rigid material with the flexible wiring board; and arranging a light-emitting element on the insulation layer formed on the first rigid material, arranging a light-receiving element on the insulation layer formed on the second rigid material, and arranging a flexible optical waveguide, which optically connects the light-emitting element and the light-receiving element, on the exposed part of the flexible wiring board.
