<P>PROBLEM TO BE SOLVED: To provide a practical cutting tool having high chipping resistance, by sufficiently applying characteristics of a complex fiber to the cutting tool when the complex fiber formed of a complex-fiber-like core material having high toughness and a covering layer is applied to the cutting tool. <P>SOLUTION: The cutting tool 1 comprises a complex structure 15 where a plurality of complex fibers 13 are arranged in random directions. Each of the complex fibers 13 comprises the core material 11 and the covering layer 12 that covers the outer periphery of the core material 11 and has composition different from that of the core material 11. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
