Results are presented on a search for new heavy leptons, a sequential heavy lepton L±, and an electron-type neutral heavy lepton E0, using the JADE detector at PETRA. No evidence for either of these particles was observed. A lower mass limit for the L± is determined to be 18.0 GeV/c2 at 95% CL. Lower mass limits for the E0 are 24.5 GeV/c2 and 22.5 GeV/c2, in the case of universal V + A and V - A coupling at the W-e-E vertex, respectively.
