An optical fiber ribbon is formed by connecting a plurality of optical fiber colored core wires to each other with a connector formed of a UV curable resin. Each of the optical fiber colored core wires includes: a bare optical fiber; a primary layer that comprises a UV curable resin that covers the bare optical fiber; a secondary layer that comprises a UV curable resin that covers the primary layer; and a colored layer disposed outside the secondary layer and that comprises a colored UV curable resin. The primary layer has a Young's modulus that is greater than or equal to 75% of a saturated Young's modulus of the primary layer.
