PROBLEM TO BE SOLVED: To provide a grinding wheel which enables a blade to be thinned, improves a yield of a workpiece, and is suitable for precision work by restraining clogging of the grinding wheel and chipping of the workpiece by efficiently removing a grinding debris by excellently circulating grinding water in grinding work. SOLUTION: This grinding wheel 1A (1B) is formed in a ring shape having a through-hole 2 in the center. A plurality of saw blade-shaped projections 3 having an acute angle corner part 3a on the tip, are continuously formed in the peripheral direction on the outer periphery. The whole grinding wheel 1A (1B) is integrally molded by a sintered body formed by simultaneously sintering an abrasive grain 4 and a binding material 5. COPYRIGHT: (C)2005,JPO&NCIPI
