PROBLEM TO BE SOLVED: To provide a method capable of simply manufacturing without enlarging a wiring space even in the case of an optical fiber sheet where the array of a plurality of optical fibers is inverted.SOLUTION: A manufacturing method of an optical fiber sheet is such that an optical fiber group 20 is fully wired on the surface of an adhesive layer 14 of a base material 10 with the adhesive layer along a predetermined wiring route R from a route change point C' to a first end part 20a side, and is temporarily wired in the direction from the predetermined wiring route R from the route change point C' to a second end part 20b side; a belt-like fixing part 28 is formed in the second end part 20b of the optical fiber group 20; the optical fiber group 20 of the temporarily wired portion is separated from the surface of the adhesive layer 14; the optical fiber group 20 separated from the surface of the adhesive layer 14 while reversing the front and the back of the band-like fixing part 28 is adhered on the surface of the adhesive layer 14 so as to become main wiring along the predetermined wiring route R.SELECTED DRAWING: Figure 4 |
