Abstract
Provided is an intermittently coupled-type optical fiber ribbon in which, in a state where a plurality of optical fibers are arranged in parallel, coupling portions at which adjacent optical fibers are coupled by a coupling resin and non-coupling portions at which the adjacent optical fibers are not coupled are intermittently provided in a longitudinal direction, the coupling portions and the on-coupling portions being provided between some or all of the plurality of optical fibers, in which at least some of the non-coupling portions include a convex portion of the coupling resin, a tip end of the convex portion having an acute angle in a cross-sectional view in a direction orthogonal to the longitudinal direction.
