Abstract
The present invention provides a photo-electric combined substrate comprising an electric interconnection part having an electric interconnection layer and an electric insulating layer as well as an optical waveguide part consisting of a core and a clad, where the electric insulating layer in the electric interconnection part and the optical waveguide part are made of the same material; a ceramic substrate comprising an optical device and an electric device where a ceramic substrate has a concave where the concave is filled with a resin, and where at least an optical device is mounted on the ceramic substrate while an electric device on the resin in the substrate concave; and an optical waveguide comprising a core and a clad having a refractive index lower than that of the core, where the core is made of a fluorene-unit-containing epoxy acrylate resin.
