Abstract:
An optical-electrical wiring board, comprising:an electrical wiring board having a through-hole formed therein; an optical wiring layer laminated on said electrical wiring board and including a core through which the light is propagated and a clad surrounding said core; and a mirror; said electrical wiring board including an electrical wiring formed on a first surface and mounting unit configured to mount an optical part and to be electrically connected to said electric wiring and mounted in the vicinity of said through-hole of said first surface; said core including a first waveguide to propagate the light in a first direction along said electrical wiring board and a second waveguide to propagate the light in a second direction perpendicular to said electrical wiring board, said second waveguide crossing the first waveguide and a part of said second waveguide being arranged within said through-hole; and said mirror arranged in the crossing point between said first waveguide and said second waveguide and serving to reflect the light propagated through one waveguide toward the other waveguide.
