Optoelectric composite substrate and method of manufacturing the same

摘要

An optoelectric composite substrate of the present invention includes an insulating film, an optical waveguide embedded in the insulating film in a state that an upper surface is exposed from the insulating film, a via hole formed to pass through the insulating film, a conductor formed in the via hole, and a connection terminal on which an optical device is mounted and which is connected to an upper end side of the conductor, wherein the connection terminal is embedded in an upper-side portion of the via hole or is projected from the insulating film.
