Using the Higgs boson mass m_h=125 GeV, the radiative Higgs decays h→γν_lν̅_l with ν_l = ν_e, ν_μ and ν_τ are analyzed in the standard model. Our calculation shows that the inclusive width of these processes, i.e., the sum of Γ(h→γν_lν̅_l) for ν_l=ν_e,ν_μ,ν_τ, is 1.41 keV, which is about 15% of Γ(h→γγ). Therefore, the observation of these channels in the future precise experiments may provide us some useful information on the Higgs physics both in the standard model and in its possible extensions.
