Next-to-MSSM is a viable model which is equipped with two features suited for electroweak baryogensis (EWBG): first-order phase transition not restricted by the Higgs spectrum and tree-level CP violation in the Higgs sector free from the nEDM constraints. We study the model when the expectation value of the singlet scalar is of the weak scale. Then the vacuum stability condition puts a novel upper bound on the charged Higgs mass. We determined allowed parameter region by requiring that the each Higgs boson is heavier than 114GeV or its coupling to Z boson is smaller than 0.1.
