Abstract:
In the cutting insert of the present invention, the cutting edge portion includes: a first corner edge; a major cutting edge continuous with a first end portion (S 1 ) of the first corner edge near the short-side-direction side surface and formed into a straight line; a first minor cutting edge continuous with a second end portion (S 2 ) of the major cutting edge and formed into a circular arc; and a second minor cutting edge continuous with a third end portion (S 3 ) of the first minor cutting edge and formed into a straight line. In a cross-sectional view of a rake face of the second minor cutting edge perpendicular to the second minor cutting edge, a cross-sectional ridgeline of the rake face of the second minor cutting edge is formed into a convex shape protruding above a cross-sectional ridgeline of a reference plane.

Claim (Index 12):
The cutting insert according to  claim 2 ,\n wherein the top surface and the bottom surface each comprise a breaker surface which constitutes a rake face of the cutting edge portion and is continuous with the reference plane, and wherein an angle between the breaker surface and the reference plane near the first corner edge is smaller than that near the second minor cutting edge.
