A composite sintered compact containing at least a cubic boron nitride and a binding material, characterized in that a plurality of cubic boron nitride particles are bound to each other, and thereby the cubic boron nitride has a continuous structure, and a plurality of binding material particles being present in the region except the binding interface, in which the above cubic boron nitride particles are bound to each other, and thereby the binding material also has a continuous structure. |
