ツプ。[Claims for Utility Model Registration] A recess is formed in the upper corner of a base material having a polygonal flat plate shape, and a cutting edge made of an ultra-high pressure sintered body is joined to this recess. In a throw-away chip in which a cutting edge is formed on a ridgeline portion facing outward from the material, a flat portion that is approximately parallel to the bottom surface of the base material is formed in a portion of the cutting edge portion that is continuous with the cutting edge, and this flat portion is 1. A throw-away chip, characterized in that the surface of the cutting edge connected to the flat part is an inclined surface that gradually approaches the bottom surface of the base material as it goes inward from the flat part.
