Using the published Kamiokande data of the multi-GeV atmospheric neutrinos, we have searched the optimum set of the neutrino oscillation parameters among three flavors. It is found that χ2 is minimized for (Δm212, Δm312) = (3.8× 10-2~eV2, 1.4× 10-2~eV2), (θ12, θ13, θ23) = (19^∘,43^∘,41^∘) with χ\rm min = 3.2 (42%CL). The sets of parameters (Δm212, Δm312) = (\cal O(10-11eV2) or \cal O(10-5eV2), \cal O(10-2eV2)) which are suggested by the two flavor analysis fall within 0.7σ.
