Abstract (en)
An object of the present invention is to provide a grinding material in which grinding portions can be increased in thickness while a decrease in grinding rate is inhibited. The grinding material according to the present invention includes a base, and a grinding layer overlaid on a front face side of the base and containing abrasive grains and a binder. The grinding layer includes a plurality of columnar grinding portions. The plurality of the grinding portions are configured so that the grinding portions are arranged in a staggered manner. The average thickness of the grinding portions is no less than 300 µm. The area of a top face of each of the grinding portions is no less than 6 mm<sup>2</sup>. The average thickness of the base is no less than 300 µm and no greater than 3,000 µm.
