Abstract

A cutting tool (1) having excellent chip treatability and adhesion resistance is provided. The cutting tool (1) includes a hard sintered body (4) in at least a cutting edge and has a rake face (2) and a flank face (3). The rake face (2) has a chip breaker (5) in a protruded or uneven shape. The hard sintered body contains at least 20% by volume of cubic boron nitride. A region of not more than 20 µm from a surface of the hard sintered body (4) on the rake face side includes A-structures made of cubic boron nitride and B-structures made of at least one selected from the group consisting of hexagonal boron nitride, amorphous boron nitride, and boron oxide. The volume ratio of the B-structures to the sum of the A-structures and B-structures, B/(A+B), is not less than 5% by volume and not more than 90% by volume.
