Abstract:
Linear abrasive members (10A, 10B) are used as abrasive members for a polishing brush. The linear abrasive members (10A, 10B) comprise inorganic long fibers and a resin which is cured after having the inorganic long fibers immersed therein. The inorganic long fibers comprise 80-90 wt% of an alumina component and 20-10 wt% of a silica component.
