Abstract
A second light guide is formed by filling, with a core material, a groove that is formed on the top surface of a reception-side substrate. A first light guide is formed by filling, with a core material, a groove that is formed on the bottom surface of a sending-side substrate. The reception-side substrate and the sending-side substrate are bonded to each other with a cladding layer interposed in between so that the second light guide and the first light guide are isolated from each other optically.
