Recent observation of a potential a deficit in the anti-neutrino flux measurement at reactor experiments may suggest the possibility of sterile neutrino species with up to eV^2 mass-square scale. The upward neutrinos at the IceCube/DeepCore observatory provide an ideal test of the sterile neutrinos, as the very long distance through the Earth and matter effect allow the sterile species significantly impact the nu_mu -> nu_e transition possibility. We analyze the constraint on the sterile neutrinos with the IceCube's measurement of the angular distribution of muon neutrino events.
