Method of manufacturing an optical-electrical wiring board

摘要

Disclosed is an optical-electrical wiring board (10), comprising an electrical wiring board (11) having a through-hole formed therein and an optical wiring layer (12) laminated on the board (11) and including a core (120) and a clad (121) surrounding the core (120). The electrical wiring board (11) includes an electrical wiring formed on one surface of the board (11) and pads (15, 17) on which optical parts are mounted. The pads (15, 17) are electrically connected to the electrical wiring and arranged on one surface of the electrical wiring board (11) in the vicinity of a through-hole. The core (120) includes a horizontal waveguide (120a) for propagating the light beam in a horizontal direction along the electric wiring board (11) and a vertical waveguide having a part arranged inside the through-hole and crossing the horizontal waveguide (120a). The vertical waveguide propagates the light beam in a direction perpendicular to the electric wiring board (11).
