The observability of charged Higgs bosons 
has been investigated at future lepton collider in type I two-Higgs- doublet model (2HDM) at the center of mass energy 
TeV. The signal process chain is 
. The process proceeds through virtual 
and Z boson exchange in the s channel. Several benchmark points are selected, and events are analyzed to reconstruct the mass of charged Higgs bosons 
. The value of 
is kept relatively high to enhance the branching ratio of 
to benefit the signal processes. The main standard model (SM) background process produced is 
. Signal selection and significance efficiencies are calculated at integrated luminosities of 100 fb
, 500 fb
, 1000 fb, and 5000 fb. The reconstructed and corrected mass of charged Higgs bosons is determined. Analyzing the results demonstrates that charged Higgs bosons can be discovered through the pair production process via its bosonic decays. This study is supposed to provide the experimentalists with a good way to examine the Higgs bosons beyond SM and to check the validity of 2HDM models in considered parameter space.
