Abstract
A grinding wheel includes an annular base and a plurality of abrasive members fixed to the lower surface of the base and arranged annularly. The base has a plurality of through holes for discharging a grinding water. The plural through holes radially extend from the inner side surface to the outer side surface of the base. The plural through holes are arranged at given intervals in the circumferential direction of the base so that the grinding water is scattered in different directions from the through holes.
