A method for manufacturing an optical fiber array by connecting bare fibers to connection elements in a facing arrangement, comprising a step of aligning a plurality of bare fibers using a bare-fiber guide; a step of bringing a flat member into contact with the aligned bare fibers, tacking the bare fibers onto the flat member by direct or indirect bonding means while keeping the bare fibers sandwiched between the bare-fiber guide and the flat member, and separating the bare fibers and the bare-fiber guide thereafter; and a step of forming a coating of uncured material on the external peripheral surfaces of the tacked bare fibers and on the flat member exposed between the bare fibers, curing this material, and bonding the bare fibers to the flat member. This method dispenses with the need to provide a bare fiber guide member and allows manufacturing costs to be reduced.
