Claim 1:
2. A pattern formation part forming a fiber optic pattern on the surface, the pattern formation part being comprised of:
a leno-weave fabric made by interweaving first and second warp yarns with first weft yarns which are fiber optic weft yarns, with the first warp yarns and the second warp yarns being twisted in opposite direction around the first weft yarns,
the first weft yarns forming a fiber optic pattern on the surface, and both the first warp yarns and the second warp yarns being transparent warp yarns that transmit at least part of light,
wherein the pattern forming part further comprises: second weft yarns which are alternately arranged with the first weft yarns next to each other as seen on the same plane of the pattern formation part, and
