ABSTRACT:
An optical waveguide having a optical waveguide path capable of securing a high light propagation characteristic regardless of the type of a supporting base, provided with a multilayer circuit board, an optical waveguide path arranged on the multilayer circuit board, a light receiving element, IC chips, and a light emitting element, the optical waveguide path formed on a transparent substrate excellent in flatness and transferred to the multilayer circuit board. The light propagation loss becomes small, and a signal to be transmitted at a high speed being transmitted as a light signal and a signal which can be transmitted at a relatively low speed being transmitted as an electrical signal, whereby the signal propagation delay which becomes the problem when a signal is transmitted by only electrical wiring is overcome, and the influence of electromagnetic noise becomes small.
