Provide is an optical fiber ribbon whereby a tape forming member can be easily removed after single core separation. The present invention is provided with: a plurality of optical fiber cores (10a, 10b) arranged in parallel spaced from each other; and a tape forming member (20) having coating portions (21a, 21b) covering an outer circumference of the optical fiber cores (10a, 10b), and a coupling portion (22a), integrally formed with the coating portions (21a, 21b), intermittently coupling adjacent optical fiber cores (10a, 10b), wherein the coating portions (21a, 21b) have opening portions (31, 32) to expose parts of surfaces of the optical fiber cores (10a, 10b), and at least a part of the coating portions (21a, 21b) is continuous in a longitudinal direction of the optical fiber cores (10a, 10b).
