Abstract
A sintered body includes cubic boron nitride grains as hard phase grains, and has a thermal conductivity of less than 20 W·m·K, for cutting a nickel-based heat-resistant alloy formed of crystal grains having a coarse grain size represented by a grain size number of 5 or less defined by ASTM standard E112-13. A cutting tool includes this sintered body. Accordingly, the sintered body having high fracture resistance in addition to high wear resistance, as well as the cutting tool including the sintered body are provided.
