We have searched for unstable charged scalar particles (S±) such as technipions or charged Higgs particles pair produced in high energy e+e- annihilation. No evidence for such particles was observed in both decay modes e+e-→S+S-→(τν) (hadrons) and → (τν)(τν). Upper limits of 4 to 11% are obtained for the branching ratio S∓ mass range between 4 to 12 GeV.
