摘要：A cutting insert which is less prone to fracture is provided in consideration of the arrangement of wiper edges. A cutting insert comprises two opposing first and
second end surfaces (2, 3) whose contour shapes are each substantially polygonal and a peripheral side surface (4) connecting these end surfaces, wherein a corner cutting edge
(6), a first cutting edge (7), a second cutting edge (8), which is on the side opposite to the first cutting edge with respect to the corner cutting edge, and a wiper edge (9) formed between the second cutting edge and the corner cutting edge, are formed at least in part of an intersecting edge between the first end surface and the peripheral side surface. In the peripheral side surface, when regarding a side surface part of the wiper edge as a wiper-edge side surface (14) and a direction perpendicular to the second cutting edge as a direction V as viewed from a direction facing the first end surface, in a side view from the direction V, the boundary of the wiper-edge side surface which is close to the second side surface is inclined with respect to a direction perpendicular to the first end surface, and the wiper-edge side surface has a constant width between the first and second end surfaces.
