Abstract
A composite sintered compact containing high density boron nitride, which consists of zincblende-type boron nitride, wurtzite-type boron nitride, ceramic material and metal in a specifically limited mixing ratio and has a high abrasion resistance, can be obtained under a relatively mild sintering condition and can be easily worked into a cutting tool.
