Abstract

A rotary polishing tool (1) comprises a disk-shaped polishing portion (3) corresponding to a workpiece (2) and a disk-shaped substrate (4) which is positioned on the rotary center (3a) of the polishing portion (3) for supporting the polishing portion (3). The substrate (4) is provided with a mounting hole (8) through which a driving shaft (10) is passed on the rotary center (3a). The substrate (4) is made of metal and is provided with a lot of holes (5), and there is provided a rubber layer (6) which is interposed between the polishing portion (3) and the substrate (4) and vulcanized and bonded to the polishing portion (3) and the substrate (4) to fix the polishing portion (3) and the substrate (4) to each other. <IMAGE>
