PROBLEM TO BE SOLVED: To provide a cubic boron nitride composite polycrystal having excellent abrasion resistance, a production method thereof, and a cutting tool, an abrasion resistant tool and a grinding tool each equipped with the polycrystal.;SOLUTION: A cubic boron nitride composite polycrystal 10 comprises: granular cubic boron nitride 1; and laminar boron nitride 3. The laminar boron nitride 3 has contact with the granular cubic boron nitride 1, and tabular boron nitride 2 is laminated on the laminar boron nitride 3. The tabular boron nitride 2 at least includes one of cubic boron nitride and wurtzite type boron nitride. The area of the tabular boron nitride 2 is 0.5% or more and 30% or less, in an area ratio to the whole surface area.;COPYRIGHT: (C)2014,JPO&INPIT
