PROBLEM TO BE SOLVED: To provide a composite sintered body containing diamond high in wear resistance, local wear resistance, and chipping resistance.SOLUTION: A composite sintered body comprises a first phase and a second phase. The first phase is a diamond phase, and the second phase is a phase formed of one or more elements or compound, or both of them imparting distortion to the first phase. The content of the second phase is 1,000 ppm or less. |
