An optical fiber ribbon includes a plurality of optical fibers each including a glass fiber including a core and a cladding covering the core, and a resin coating covering the glass fiber, the plurality of optical fibers being arranged in parallel. In the optical fiber ribbon, 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.
