Provided is an optical fiber ribbon and an optical fiber cable, which are adaptable to manufacture at a high velocity, in the intermittent connecting type optical fiber ribbon obtained by adhering and connecting adjacent colored optical fibers by intermittent connecting portions. In an optical fiber ribbon 2 of the present invention, since, in addition to polyol having a weight average molecular weight in a specific range, rheology control agent is contained in a specific range in a material forming an intermittent connecting portion 3, the Newtonian region between a low shear rate region and a high shear rate region of the material forming the intermittent connecting portion 3 can be adjusted. Thus, scattering of the material due to a centrifugal force generated by rotation of an application roll that applies the material at the time of manufacture and the like can be suppressed, and the application amount to colored optical fiber 1 can be stabilized. In addition, the optical fiber ribbon 2 can maintain suppression of such scattering and the like even in the manufacture at a high linear velocity.
