ABSTRACT:
The present invention provides a hybrid optical/electrical circuit board in which an optical waveguide prepared by an exposing and developing step is combined with an electric circuit, wherein a printed wiring board containing an inorganic filler and a light absorber is used, and it has an optical waveguide core pattern having a high resolution and makes it possible to raise a density of optical wiring.
