摘要
A polishing disc of spherical polishing device for polishing optical end surface capable of minimizing optical loss due to reflection in a returning direction. With this polishing disc of polishing device for polishing a spherical surface on optical fiber end surface, a tip end of a ferrule supporting an optical fiber is pressed against a surface of the polishing disc and a relative movement for polishing is caused between the ferrule tip end and the polishing disc surface to polish a tip end of the optical fiber into a spherical surface. The polishing disc A is constituted by a flat plate made of an elastic material and a soft plastic film which is provided on said flat plate as a film surface without containing abrasive and which has rugged patterns having a surface roughness of several microns or less. The surface of the soft plastic film is preferably a rough surface having rugged patterns of a surface roughness of 2 &mgr;m or less.
