Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a cutting tool using cBN sintered body of fine particles having dimension of 0.1 μm or less. SOLUTION: In the cutting tool for cutting an object to be cut, hexagonal boronitride is converted to a sintered body 1 of cubic boronitride by pressing it while heating the hexagonal boronitride using the hexagonal boronitride. The sintered bodies 1, 1a is made to a cutting blade part for cutting the object to be cut. Heating and pressing are performed at a temperature and a pressure that the dimension of the particle constituting the sintered body 1 is made to 0.1 μm or less. COPYRIGHT: (C)2009,JPO&INPIT
