Sumario:The precise determination of the mass, couplings and other properties of the particle discovered in 2012 around 125 GeV is important to establish precisely if it is a Standard Model Higgs boson. CMS experiment has collected lot more data since the discovery of this particle in July 2012 and has performed many of its properties measurements. In this talk, I will present some of these measurements. These measurements are based on data samples corresponding to integrated luminosities of up to 5.1 $\mathrm{fb}^{-1}$ at 7 TeV and up to 19.7 $\mathrm{fb}^{-1}$ at 8 TeV in proton-proton collisions at the LHC. The combined result for the measured mass, the best-fit signal for all the channels and different fits for couplings, using all the studied Higgs boson decay modes, will be described.
