However, in order to transmit optical signals without loss, the end face of an optical fiber is particularly required to have a precise surface finish. Polishing films and the like are used, which are obtained by applying a resin solution containing fine inorganic powder dispersed in a solution and drying the resin to form a polishing layer.

な研磨仕上げを実施し難いという欠点を有している。[Problems to be Solved by the Invention] In recent years, in optical fiber end face polishing machines that polish the end face of optical fibers, a load of approximately several kg 7' cf is applied to the tip of a connector with an optical fiber and the end is pressed against a polishing film to perform the polishing process. However, since the conventional polishing film has poor elasticity, it is easily affected by the surface condition of the support that supports the polishing film, and the surface of the polishing film sometimes occurs. This has the disadvantage that it is difficult to perform highly accurate polishing because it may be affected by convex parts or foreign matter mixed in.
