PURPOSE: To ensure a suitable elasticity and a suitable strength for a polishing base material used for a polishing tool, and to facilitate the manufacture of the polishing tool with the use of the base material.
CONSTITUTION: A plurality of polishing fibers 3 are fixed at predetermined intervals in a substantially one direction on the outer surface of a sheet-like base 2 so as to constitute a plurality of polishing fibers 3. A sufficient polishing force can be ensured by using the polishing fibers 3 as a polishing material, and further, a suitable elasticity and a suitable strength can be ensured by adjusting the resiliency and strength of the sheet-like base 2. Further, the polishing base material 1 itself has a simple structure, and has an easily handlable shape, thereby it is possible to easily constitute a polishing tool with the use of the polishing base material.
