A holder for supporting an end surface of a workpiece during polishing comprises a main body and a framework which are respectively provided with fixing portions corresponding to each other; at least one of the two fixing portions has at least one set of upper and lower contact portions, and the upper and the lower contact portions on each set are respectively disposed above and below a contact plane formed between the end surface of the workpiece and a polishing surface; when the upper and lower contact portions and another one of the fixing portions one another, the main body is capable of keeping parallel to the polishing surface, and the pressure acting on the end surface of each workpiece is capable of being approximately uniform. Hence, the number of end surfaces of the optical fibers can be increased tremendously during polishing so as to enhance the polishing speed and quality.
