A cemented carbide may include a hard phase that may include W and C, a first solid solution phase and a second solid solution phase, each of which may include W, C, Ti and Zr, and a binder phase that may include an iron group metal. The cemented carbide may include 1.0-3.0 mass % of the Ti in terms of TiC, and 0.75-2.0 mass % of the Zr in terms of ZrC. An amount of the Ti in terms of TiC may be more than 1 time and less than three times an amount of the Zr in terms of ZrC. The first solid solution phase may satisfy a relationship of 0.1≤Ti/(Ti+Zr)
