  In this paper we discuss the phenomenon of the Andreev reflection of quarks
at the interface between the 2SC and the Color-Flavor-Locked (CFL)
superconductors appeared in QCD at asymptotically high densities. We also give
the general introduction to the Andreev reflection in the condensed matter
systems as well as the review of this subject in high density QCD.
