We searched for pair production of charged Higgs bosons via e+e− annihilation, using data (23.3 pb−) collected by the TOPAZ detector in the energy range s = 52.0 – 61.4 GeV. We observed no evidence for charged Higgs pair production and extended the excluded region in the MH±BR (hadron) plane. The 95% CL lower mass limit is the most stringent for BR (hadron) = 0.6, giving mH±
