Abstract
A first optical wave guideand a second optical wave guideare connected to both sides of a planer optical waveguiderespectively. The other endsof the first and second optical wave guidesare extended over an upper surfaceof an optical wiring circuit board. An electric wiring circuitis connected to the other endsof the first and second optical wave guides, thereby constituting an optical wiring circuit. A plurality of optical wiring circuitsare superimposed on one another to thereby form an optical wiring circuits layered body. The electric wiring circuitcan be connected from one surface of the optical wiring circuit board, which makes it possible to facilitate the connection thereof.
