We have searched for possible high-energy neutrino signals which are expected from massive dark matter captured by the Earth and the Sun by making use of upward-going muon samples collected during 7 years of operation of the Kamiokande detector. No excess of events was found from the Earth or the Sun, thus giving an excluded range of parameters for the neutralino dark matter which is hypothesized to constitute the halo of the Galaxy. The upper bounds extend to a mass range of up to ∼1 TeV, which was never analyzed in previous indirect searches.
