Abstract:
A cutting insert according to an aspect includes a top surface and a side surface. At least a part of a ridge line where the top surface and the side surface intersects is a cutting edge. The cutting edge includes a first portion located at a corner portion, a second portion adjacent to the first portion, a third portion close to the second portion, a fourth portion close to the third portion, and a fifth portion adjacent to the fourth portion. When viewed from directly above, a curvature radius of the second portion is less than a curvature radius of the first portion, a curvature radius of the third portion is greater than the curvature radius of the first portion, and a curvature radius of the fourth portion is less than the curvature radius of the third portion.

Claim (Index 1):
A cutting insert comprising:\n a top surface including a first corner portion and a first side portion extending from the first corner portion; and a side surface adjacent to the top surface, wherein at least a part of a ridge line where the top surface and the side surface intersects is a cutting edge, the cutting edge includes a first portion located at the first corner portion, a second portion adjacent to the first portion, a third portion close to the second portion, a fourth portion close to the third portion, and a fifth portion adjacent to the fourth portion and located at the first side portion, when viewed from directly above, the first portion, the second portion, the third portion, and the fourth portion each have a circular arc shape, and when viewed from directly above, a curvature radius R 2  of the second portion is less than a curvature radius R 1  of the first portion, a curvature radius R 3  of the third portion is greater than the curvature radius R 1  of the first portion, and a curvature radius R 4  of the fourth portion is less than the curvature radius R 3  of the third portion.
