Abstract:
1. An apparatus comprising: a layered board including an optical layer includes an optical waveguide layer capable of transmitting the optical signal in a planar manner in said waveguide layer; a second layer capable of transmitting at least one of an electrical signal and an optical signal; an insulating layer interposed between the optical layer and said second layer; a signal connecting path penetrating said insulating layer, said signal connecting path establishing interconnection of a signal between said optical layer and said second layer, and said signal connecting path performing both a function of transmitting an electrical signal and a function of transmitting an optical signal; means for transmitting and receiving a high-frequency signal; and means for processing the high-frequency signal, wherein said optical waveguide includes one of a conical and hemispherical light scattering structure, said light scattering structure being disposed in said optical waveguide layer, and a signal being transmitted between said signal connecting path and said optical waveguide layer through said light scattering structure, and wherein said apparatus is incorporated in a cellular phone.
