Insert and cutting tool

An insert, comprising:

• a boron nitride sintered body comprising a first surface, a second surface, and a cutting edge located on at least a part of a ridge part of the first surface and the second surface,
• the boron nitride sintered body comprising cubic boron nitride and compressed boron nitride,
• wherein
• in a transmission X-ray diffraction of a cross section of the boron nitride sintered body vertical to the first surface,
• in a direction vertical to the first surface
• X-ray intensity at a top of a 111 diffraction peak of the cubic boron nitride is IcBN(111)v, and X-ray intensity at a top of a 002 diffraction peak of the compressed boron nitride is IhBN(002)v, and
• in a direction parallel to the first surface
• X-ray intensity at a top of a 111 diffraction peak of the cubic boron nitride is IcBN(111)h, and X-ray intensity at a top of a 002 diffraction peak of the compressed boron nitride is IhBN(002)h,
• a compressed boron nitride content value indicated by
• (IhBN(002)v+IhBN(002)h)/(IcBN(111)v+IcBN(111)h) is larger than 0.002 and smaller than 0.01,
• a cubic orientation value indicated by IcBN(111)v/(IcBN(111)v+IcBN(111)h) is larger than 0.5, and
• a compressed boron nitride orientation value indicated by
• IhBN(002)v/(IhBN(002)v+IhBN(002)h) is larger than the cubic orientation value.
