Cemented carbide and cutting tool

A cemented carbide comprising a plurality of tungsten carbide grains and a binder phase,

• wherein the cemented carbide comprises the tungsten carbide grains and the binder phase in a total of 89% by volume or more,
• the cemented carbide comprises 1.5% by volume or more and 23% by volume or less of the binder phase,
• the binder phase contains 40% by mass or more of cobalt,
• the binder phase contains silicon, and the binder phase further contains at least one first element selected from the group consisting of phosphorus, and tin,
• the first element is not segregated in a first interface region between the tungsten carbide grains that are adjacent to each other, and
• the first element is not segregated in a second interface region between the tungsten carbide grain and binder phase that are adjacent to each other,
• in the binder phase, a percentage {M1/(M1+M2)}×100 of a mass M1 of the first element to a total M1+M2 of the mass M1 of the first element and a mass M2 of cobalt is 1% or more and 6% or less.
