ABSTRACT:
In order to avoid a frequent multiple crossing in an optical fiber in a sheet and attach the optical connector near a marginal end of the sheet while maintaining a sufficient extra length and more extra length for attaching the optical fibers, in the optical fiber sheet6, an optical fiber5as an extra length section in the optical fiber path is disposed on three-layer wiring planes which are formed by attaching four sheets1, 2, 3, and4. Notched sections2aand3aare formed in the intermediate layers2and3. The optical fiber5communicates from a first wiring layer to a second wiring layer via the notched section2aso as to communicate from the second wiring layer to a third wiring layer via the notched section3a.
