PURPOSE: To obtain a polisher which can continuously polish an optical element such as lens with high precision in a short time, by mixing at least one between graphite powders and carbon whiskers with epoxy resin.

CONSTITUTION: A polisher for polishing an optical element such as a lens in constituted by mixing at least one between graphite powders and carbon whiskers with epoxy resin. When the polisher is manufactured, the mixture 1 is stirred by a stirring rod 2 and then dripped on a base plate 3. Then, the base plate 3 is fixed on a polisher manufacturing tool 4, and after a mating plate 5 coated with a mold releasing agent 6 is installed on the tool 4 from over the base plate 3, the mating plate 5 is pushed on the mixture 1 from the upper. Then, this article is accommodated into a thermostatic over, and hardened under a constant. temperature. After cooling, the polisher is separated from the mating plate 5, and a groove for the flow of polishing liquid is formed, and thus the polisher is completed.
