Abstract
We discuss CP violation in the process e^+e^- \to \tilde\chi^+_i\tilde\chi^-_j with unpolarized beams. When the scalars are heavy, the box-diagram results constitute a major part of the full result. However, there are situations when the vertex and self-energy corrections dominate over the box diagrams. We also comment on CP violation in the final chargino decay.
