The apparatus includes a ferrule holder having a holder block capable of sandwiching a cylindrical portion of a ferrule, and a guide block for guiding the ferrule to the holder block; a polisher having a rotatable polishing board for polishing an axial end-surface of the ferrule held by the ferrule holder; and a ferrule transfer device for transferring and loading the ferrule into the ferrule holder, and for removing the ferrule therefrom after polishing. With this configuration, the ferrule polishing operation is automated.
