表面を傷つけることなく研磨ができる。Further, since the abrasive grain fibers or the abrasive grains can be adhered to desired positions on the surface of the bag-shaped elastic body, for example, a bundle of abrasive grain fibers or a polishing layer composed of the abrasive grains is formed on the bag-shaped elastic body surface. If formed at intervals, abrasive debris is removed to the outside through the intervals, so especially in the case of abrasive fibers,
Since the abrasive grain fibers are not attached to each other, polishing debris can be taken in between the fibers and polishing can be performed without damaging the surface to be polished by the polishing debris.
