Abstract:
1. A layered board comprising: an optical layer includes an optical waveguide layer capable of transmitting an optical signal in a planar manner in the waveguide layer; a transmitting layer capable of transmitting at least one of an electrical signal and an optical signal; an insulating layer interposed between said optical layer and said transmitting layer; a signal connecting path penetrating said insulating layer, said signal connecting path establishing interconnection of signals between said optical layer and said transmitting layer, and said signal connecting path performing both a function of transmitting the electrical signal and a function of transmitting the optical signal; and a light scattering structure being one of a conical configuration and a hemispherical configuration, said light scattering structure being disposed in said optical waveguide layer, and the signal being transmitted between said signal connecting path and said optical waveguide layer through said light scattering structure.
