PURPOSE: A spinneret for discharging a polymer being small in size as compared to conventional polymer chips is provided. It enables the ratio between the diameter of a spinneret hole to the length of the spinneret to be stably maintained and thus can produce a fine size of chips without the generation of overlapping(adhesion between chips). It also can be used in the manufacture of a yarn, film and plastic for special application in the post process. CONSTITUTION: The spinneret for discharging a polymer has a length and a diameter of a spinneret hole(15) satisfying the following formula:1.549ZD/LZ2.45, 5.05ZDPREC6.20. In formula, D is a diameter(mm) of the spinneret hole, L is a length of the spinneret. Polymer chips prepared through the spinneret for discharging a polymer have a diameter of 1.8 to 2.0mm and a length of 2.8 to 3.0mm.
