Abstract
A wire-shaped grinding element (10A, 10B) is used as a grinding element for a polishing brush. The wire-shaped grinding element (10A, 10B) includes inorganic filaments and a resin that impregnates the inorganic filaments and is cured. The inorganic filaments contain 80 to 90% by weight of an alumina component and 20 to 10% by weight of a silica component. The crystal structure of the inorganic filaments includes intermediate alumina. The silica component is in an amorphous state. The BET specific surface area of the inorganic filaments is 30 m2/g or smaller.
