A search for sequential charged leptons decaying into massive neutrinos has been performed at E/sub c.m./ = 56 GeV at the KEK collising-beam accelerator TRISTAN. We have found no evidence for the production of the charged heavy leptons for an integrated luminosity of 5.3 pb/sup -1/. A search for stable charged leptons was also conducted yielding null results. A new mass limit on the charged heavy leptons was obtained as a function of the mass of the associated neutrinos.
