A sintered body having low reactivity with a workpiece while maintaining high strength and hardness, and a cutting tool excellent in wear resistance are provided. A sintered body containing cubic boron nitride, at least one of cubic sialon and cubic silicon nitride, and a first compound, the content of cubic boron nitride being 35 volumes. The cubic boron nitride is particles having an average particle diameter of 0.5 μm or more and 5 μm or less, and the total content of the cubic sialon and the cubic silicon nitride is 2% by volume. 65 vol% or less, and the first compound comprises at least one element selected from the group consisting of Group 4 elements, Group 5 elements, Group 6 elements and aluminum, and a group consisting of nitrogen, boron and carbon A sintered body having at least one compound selected from the group consisting of at least one element and having a total content of the first compound in the sintered body of 10% by volume to 60% by volume.
