Abstract: A cutting insert has a first (top) end surface, a second (bottom) end surface, a peripheral side surface connecting the top and bottom end surfaces, and a mounting hole having a central axis O which penetrates the top and bottom end surfaces. Cutting edges are formed on an intersecting edge between the first end surface and the peripheral side surface. The second end surface has an inclined part. When a virtual plane substantially perpendicular to the axis O and passing through any point of the cutting edges is defined, the inclined part is inclined so as to be more distant from the virtual plane, heading from the peripheral side surface to the axis O. A projected part projected in a direction along the axis O is formed in an area around the mounting hole in the inclined part. This reinforces the strength of the mounting hole.

Abstract: A SiC wafer is produced from an SiC ingot having an end surface by setting the focal point of a laser beam at a predetermined depth from the end surface. The depth corresponds to the thickness of the SiC wafer to be produced.
