A cemented carbide including tungsten carbide grains and a binder phase, in which a total content of the tungsten carbide grains and the binder phase in the cemented carbide is no less than 80 vol %, a content of the binder phase in the cemented carbide is no less than 0.1 vol % and no more than 20 vol %, in a histogram showing distribution of orientation differences between adjacent pairs each consisting of two of the tungsten carbide grains adjacent to each other in the cemented carbide, a first peak is present in a class of the orientation differences of no less than 29.5° and less than 30.5°.
