1. An optical fiber ribbon comprising:
a plurality of optical fibers each including a glass fiber including a plurality of cores and a cladding covering the plurality of cores, and a resin coating covering the glass fiber, the plurality of optical fibers being arranged in parallel,
wherein a distance between central axes of adjacent optical fibers among the plurality of optical fibers in a direction orthogonal to a longitudinal direction of the plurality of optical fibers is larger than an outer diameter of each of the plurality of optical fibers,
wherein a respective reference line that passes through centers of two or more cores of the plurality of cores is different between the adjacent optical fibers; and
a dummy line disposed between the adjacent optical fibers,
wherein the dummy line and the adjacent optical fibers are intermittently bonded to each other in the longitudinal direction, and
wherein the dummy line and the adjacent optical fibers are structurally different from each other.
