Abstract
An optical fiber ribbon includes a plurality of colored single fibers that are arranged side by side, and the adjacent single fibers are coupled by coupling resin. The single fibers are disposed leaving a gap between the single fibers. The adjacent single fibers are bonded to each other intermittently by coupling parts at predetermined intervals in a longitudinal direction. That is, the coupling parts between the adjacent single fibers are disposed intermittently with regard to the longitudinal direction of the single fibers. The coupling parts are formed of opaque coupling resin. A haze value of the coupling resin according to JIS K 7136 is preferably between 1.5% and 3%, for example.
