Optical waveguide, optical interconnection component, optical module, opto-electric hybrid board, and electronic device

Abstract

In accordance with the present invention, an opto-electric hybrid board in which optical wiring is freely disposed without restriction by the arrangement of electrical elements and the like, and in which high-density mounting of electrical wiring and optical wiring is possible, and an electric device including this opto-electric hybrid board are provided. An opto-electrical hybrid board () of the present invention has an optical waveguide (), an optical connector disposed at an end section of the optical waveguide (), and an opto-electric conversion section () disposed below the optical waveguide (), and a motherboard (electrical wiring board) () disposed below the opto-electric conversion portion (). Of these, the optical waveguide () includes a core layer () including a plurality of core sections () being configured to intersect with each other at one plane and side surface cladding sections, and a mirror (optical path conversion section)converting the optical path of the core sections (). Also, between the optical waveguide () and the motherboard () is connected via an electrical connector and preferably both the optical waveguide () and the motherboard () are detachable.
