A superabrasive wheel (100, 200) for mirror finishing comprises an annular base plate (120, 220) having an end surface (121, 221) and a plurality of superabrasive layers (110, 210), each having a peripheral end surface (111), arranged along the peripheral direction of the annular base plate (120, 220) at intervals from each other and fixed onto the end surface (121, 221) of the base plate (120, 220). Each of the plurality of superabrasive layers (110, 210) has a flat plate shape, and is so arranged that the peripheral end surface (111) is substantially parallel to the rotary shaft of the superabrasive wheel (100, 200). A surface (113) defined by the thickness of the flat plate shape of each of the plurality of superabrasive layers (110, 210) is fixed onto the end surface (121, 221) of the base plate (120,220). In the superabrasive layers (110, 210), superabrasive grains are bonded by a binder of a vitrified bond. In another superabrasive wheel (300, 400) for mirror finishing, each of a plurality of superabrasive layers (310, 410) has an angularly bent plate shape, and is so arranged that a peripheral end surface (311) is substantially parallel to the rotary shaft of the superabrasive wheel (300, 400).
