A cemented carbide includes a plurality of tungsten carbide particles and a binder phase, wherein the cemented carbide comprises at least one first element selected from the group consisting of titanium, tantalum, niobium, zirconium, cerium, yttrium, and boron, and wherein in a first graph in a coordinate system where an X axis is a distance from a position at which cobalt exhibits a maximum intensity, and a Y axis is a normalized intensity, a maximum peak M of each of the first element is present between a peak W1 of tungsten closest to an origin and a further peak W2 of tungsten closest to the peak W1, a ratio IB/IA of an intensity IB to a maximum peak intensity IA of the maximum peak M is 0.5 or less in each of the first element, and the intensity IB is an intensity of the first element at a distance P2.
