PROBLEM TO BE SOLVED: To obtain a cemented carbide, having high hardness and high toughness and a cutting tool using the cemented carbide which has excellent wear resistance, plastic deformation resistance and chipping resistance against the highly efficient cutting of a hardly machinable material such as a stainless steel. SOLUTION: The cemented carbide comprises a tungsten carbide phase, a solid solution phase consisting of at least two kinds of carbide, nitride and carbonitride of metals selected from the groups 4a, 5a and 6a in the periodic table containing at least Zr and Nb, and a binder phase containing at least one kind of ferrous metal, and the X-ray diffraction peak has a first peak with a peak top at 2θ=40.00-41.99 deg., and a second peak with a peak top at 2θ=38.00-39.99 deg..
