Abstract
A brush-like grinding stone (1) includes a linear grinding member (11) obtained by stiffening, with a resin binder, a composite yarn including inorganic filaments. As the linear grinding member (11), a linear grinding member (11A) having a square cross-sectional shape, a linear grinding member (11B) having a rectangular cross-sectional shape, or a linear grinding member (11C) having an elliptical cross-sectional shape is used. While the linear grinding member (11A) is hard to bend in the diagonal directions of the cross section, the linear grinding member (11B) and the linear grinding member (11C) are hard to bend in directions along the long side and the major axis, respectively, of the cross section. Thus, each of the linear grinding members (11A to 11C) has an edge effect and provides high grading performance.
