Zusammenfassung:	PURPOSE:To manufacture a high pressure phase BN sintered body having exceedingly improved cuttability by blending high pressure phase BN constituted of cBN and wBN blended under specified conditions with a bonding phase of intermetallic compounds constituted of the carbide or the like of the 4a in a periodic table with an Al metal or the like in specified ratios. CONSTITUTION:A high pressure phase boron nitride sintered body is manufactured by blending 10 to 80vol.% high pressure phase boron nitride constituted of 95 to 99.9vol.% cubic system boron nitride (cBN) having
