PROBLEM TO BE SOLVED: To provide such an optical fiber array that, since optical fibers are surely fixed to grooves formed on a substrate with a UV-curing adhesive, the displacement of the optical fibers does not occur and optical signals can be accurately transmitted even when the optical fiber array is connected to optical devices or external force is added to the optical fiber array. SOLUTION: The optical fiber array is composed of a substrate having a plurality of grooves and a holding part of a coating resin layer formed on its upper surface and of an optical fiber ribbon having a plurality of coated optical fibers arranged in parallel and a coating resin layer formed around the fibers. The coated optical fibers are fixed to the grooves with an adhesive and the coated optical fibers and the coating resin layer are fixed with the adhesive to the holding part of the coating resin layer. The adhesive is a hardened product of an epoxy-based or acrylate-based UV-curing resin composition.
