<P>PROBLEM TO BE SOLVED: To provide a CBN (cubic boron nitride) grinding wheel for drastically improving grinding wheel performance by taking a crystal orientation of CBN abrasive particles into account. Ž<P>SOLUTION: In the CBN grinding wheel 4 in which an abrasive particle layer 2 including the plurality of CBN abrasive particles 6 and a bonding agent 12 is formed around a core 8 attached to a grinding wheel spindle 42 pivoted by a wheel spindle stock 41 of a grinder 40 around an axis of revolution, the respective CBN abrasive particles 6 are single crystal leaf-form abrasive particles including a ä111} surface A which is widest of the CBN abrasive particles 6 and a ä111} surface B parallel to the ä111} surface A. In the abrasive particle layer 2, the ä111} surfaces A and the ä111} surfaces B of the respective CBN abrasive particles 6 are arranged at a right angle to an outer circumferential surface of the grinding wheel.
