PROBLEM TO BE SOLVED: To provide a diamond polycrystal body that is excellent in abrasion resistance; a production method of the same; and a cutting tool and an abrasion resistant tool including the polycrystalline material.SOLUTION: A diamond polycrystal includes: cubic diamond; and hexagonal diamond. A fraction of X-ray diffraction peak strength relating to (100) face of the hexagonal diamond to X-ray diffraction peak strength relating to (111) of the cubic diamond is larger than 0.5%. |
