Observation of the prompt neutronization burst by Kamiokande II is shown to constrain the mixing parameter sin2θ{symbol} of a 10-100 eV mass range neutrino less than 10-7, implying that the neutrino is unlikely to provide the critical mass of the universe except in a special case of a neutrino decoupled from other lighter neutrinos. Model dependent bounds on neutrino masses are also given for a class of neutrino mixing models.
