摘要： There are provided a cemented carbide high in thermal diffusivity and excellent in wear resistance, and a cutting tool including a base material formed of this cemented carbide. The cemented carbide is a WC based cemented carbide in which a hard phase mainly constituted of WC grains is bound by a binder phase mainly constituted of Co, and is used for a cutting tool. The binder phase is substantially constituted of Co, or Co and Ni. A total content of Co and Ni is not less than 4.5 mass % and not more than 15 mass %. In this cemented carbide, the WC grains have an average diameter of not less than 0.4 µm and not more than 4 µm. Assuming that the average diameter of the WC grain is represented by x (µm), the cemented carbide has a thermal diffusivity X (cm 2 /sec) satisfying X > 0.055x + 0.238. The cemented carbide can further contain one or more elements selected from Cr, Ta, Nb, Zr, and Ti at not less than 0.05 mass % and not more than 5 mass % in total.
