To provide a method of polishing an end face of a multi-fiber optical connector capable of eliminating recesses produced in core parts of multi-mode optical fibers. A polishing base is prepared, comprising a soft material having a Shore hardness of less than 30 and a film having a thickness of less than 75 mum, without including any polishing material, on said soft material, and further comprising a polishing material on said film. Next, a multi-fiber optical connector having a plurality of multi-mode optical fibers is arranged so that the tip of the multi-mode optical fibers come into contact with the upper surface of the film with a predetermined pressure. Next, the tip of the multi-mode optical fibers are polished by moving at least one of the polishing base and the multi-fiber optical connector while maintaining the contact between the tip of the multi-mode optical fibers and the upper surface of the film.
