やクリーニング仕上げができる。In the polishing operation and the cleaning operation using the polishing tape of the present invention, minute polishing dust and foreign matters do not adhere to the surface of the polishing tape. The surface of the object to be polished or the object to be subjected to the cleaning process is not damaged, and the pressure when the polishing tape is pressed against the object to be polished or the surface of the object to be subjected to the cleaning process is easily adjusted. Therefore, there is no insufficient polishing or insufficient cleaning due to insufficient pressure, and there is no occurrence of polishing scratches due to excessive pressure, and appropriate and uniform polishing finish and cleaning finish can be performed.
