Abstract: The present invention provides a polishing film with which, even when water containing impurity ions is used as a polishing liquid, the abrasive particles comprising SiO2 are less apt to adhere to the polished surface, e.g., the polished surface of an end of an optical fiber itself, and which is less apt to cause the optical loss attributable to scratches or edge chips in the polished surface. The polishing film hence renders good finish-polishing quality possible. This polishing film is characterized by comprising a substrate and an abrasive layer which has been disposed on a surface of the substrate and which comprises abrasive particles comprising SiO2, a binder resin, and an adhesion inhibitor containing a phosphorus compound.

Abstract: In a friction transmission belt in which a compression rubber layer provided to an inner circumferential side of the belt body is wrapped over pulleys such that the compression rubber layer contacts the pulleys, such a configuration that both of a noise reduction and durability while the belt is running can be achieved is obtained. The compression rubber layer is configured so as not to include short fibers and so as to have a surface roughness, i.e., an Ra of at least a pulley contact surface of the compression rubber layer equal to or more than 3 ?m.
