An ultra abrasive wheel for mirror finish (100, 200), comprising an annular base metal (120, 220) having an end face (121, 221) and a plurality of ultra abrasive grain layers (110, 210) disposed at intervals along the circumferential direction of the annular base metal (120, 220), fixed onto the end face (121, 221) of the base metal (120, 220), and each having a peripheral side end face (111), wherein each of the plurality of ultra abrasive grain layers (110, 210) is formed in a flat plate shape, and disposed so that the peripheral side end face (111) thereof is positioned generally parallel with the rotating axis of the ultra abrasive grain wheel (100, 200), the surface (113) specified by the thickness of each flat plate shape of the plurality of ultra abrasive grain layers (110, 210) is fixed onto the end face (121, 221) of the base metal (120, 220), ultra abrasive grains are connected to each other with the binder of the Vitrified bond in the ultra abrasive grain layers (110, 210), and the ultra abrasive grain layers may be formed in a plate shape bent in a chevron shape.
