An optical fiber multiplexing/demultiplexing devices for the multiple-fiber ribbon of optical fibers, and the fabrication method. It comprises a set of optical fibers arranged in the form of a multiple-fiber ribbon wherein an intermediate point on the multiple-fiber ribbon is first cut, the covers of the optical fibers in the multiple-fiber ribbon thus cut are removed on both sides of the cut edges by a certain length required to expose the optical fiber elements, and both edges of the optical fiber elements paired on both sides of the cut point are welded each other by arc discharge; a pair of substrates in each of which a plurality of V-grooves by the number of the optical fiber elements are provided in parallel each other at equal intervals to form an array on one side thereof, and the pair of substrates assembled so that the scrubbed sides of the surfaces in the pair of substrates are contacted each other so as to couple the cores of the optical fiber elements together according to the Evanescent wave coupling.
