We report on a search for heavy neutrinos in B-meson decays. The results are obtained using a data sample that contains 772×106BB̄ pairs collected at the Υ(4S) resonance with the Belle detector at the KEKB asymmetric-energy e+e- collider. No signal is observed and upper limits are set on mixing of heavy neutrinos with left-handed neutrinos of the Standard Model in the mass range 0.5-5.0 GeV/c2.
