• We investigate the clectroweak phase transition in the presence of a largo CP violation in the squark sector of the MSSM. When the CP violation is large, soalar-pseudoscalar mixing of the Higgs bosons occurs, and a large CP violation in the Higgs sector is induced.It, however, weakens the first-order phase transition before the mixing reaches its maximal level. Even when the CP violation in the squark sector is not so large that the phasetransition is strongly first order, the phase difference between the broken and symmetric phase regions grows to O(1), which leads to successful baryogenesis when the charged Higgs bosons are light.
