摘要：
A cutting insert may include a first surface having a polygonal shape, a second surface, and a cutting edge located on a ridge line where the first surface intersects with the second surface. The first surface may include a first corner, a second corner, a third corner, a first side, and a second side. In a plan view of the first surface, the first side may have a straight line shape or a convex shape protruded outward relative to a first imaginary line connecting the first corner and the second corner, and the second side may have a concave shape recessed inward relative to a second imaginary line connecting the first corner and the third corner.
