The new source of $CP$-violation in the frames of "charge transport" mechanism of electroweak baryogenesis is investigated. The consideration is based on the assumption that $C$ and $CP$ need not be violated at the same place, and on the fact that in the case of nonpolarized flux of fermions falling nonperpendicularily on the phase-separating domain wall the transmitted flux will be polarized (i.e. $P$ and $CP$ are violated). Sphaleron processes can convert the ($P$ and $CP$)-asymmetric state into ($C$ and $CP$)-asymmetric one. We argue that the value of $CP$-violation in such mechanism can explain the observed value of Baryon Asymmetry of the Universe even in the frames of the Minimal Standard Model.
