Abstract
Provided is an intermittently coupled optical fiber ribbon in which a bonded portion in which adjacent optical fibers are bonded by an adhesive resin and a non-bonded portion are intermittently provided in a longitudinal direction. The bonded portion is provided on one side of the optical fiber ribbon. A part of the bonded portion protrudes further than a tangent line passing through surfaces of the adjacent optical fibers on the one side. In the longitudinal direction, at least one of longitudinal end portions of the bonded portion has a larger protrusion height than a central portion of the bonded portion. The adhesive resin has a composite elastic modulus of 0.5 GPa or more and 6.0 or less at 23° C.
