Using a sample of Z 0 's corresponding to about 12 000 events, we have searched for the production of charged scalars, primarily charged Higgs particles, decaying into c sc s , τν + jets, and τντν. The average detection efficiency is 20%. No candidate was found in the leptonic modes. Masses in the range up to 30-36 GeV/ c 2 are excluded, extending the mass domain covered by previous e + e − machines.
