This insert (1) has a cBN-based sintered body containing cBN and TiN. The cBN accounts for 60% by area or more in a cross-sectional view of the cBN sintered body. Furthermore, when the X-ray intensity of the (111) crystal plane of cBN in the X-ray diffraction of the cBN sintered body is cBN (111) and the X-ray intensity of the (200) crystal plane of TiN in the X-ray diffraction of the cBN sintered body is TiN (200), TiN (200) is greater than cBN (111). 本发明的刀片(1)具有含有cBN和TiN的cBN质烧结体。在cBN质烧结体的截面观察中，cBN占60面积％以上。另外，设cBN质烧结体的X射线衍射中的、cBN的(111)晶面的X射线强度为cBN(111)，设cBN质烧结体的X射线衍射中的、TiN的(200)晶面的X射线强度为TiN(200)时，TiN(200)大于所述cBN(111)。
