Abstract
An optical bus production method for producing an optical bus having an improved transmission efficiency while preventing a data transmission failure. More specifically, the optical bus is produced by preparing first sheets that serve as a light transmission layer, a clad layer is formed on both front and rear sides of each of the first sheets and a second sheet is inserted, is prepared separately from the first sheet and serves as a clearance layer between the first sheets having the clad layer. The resulting optical bus includes a plurality of light transmission paths, each consisting of a light transmission layer and clad layers sandwiching the light transmission layer, and clearance layers for specifying the interval between the light transmission paths, each clearance layer being interposed between adjacent light transmission paths.
