The Kondo effect is a universal phenomena observed in a variety of fermionsystems containing a heavy impurity particle whose interaction is governed bythe non-Abelian interaction. At extremely high density, I study the Kondoeffect by color exchange in quark matter containing a single heavy (charm orbottom) quark as an impurity particle. To obtain the ground state with theKondo effect, I introduce the condensate mixing the light quark and the heavyquark (Kondo cloud) in the mean-field approximation. I estimate the energy gainby formation of the Kondo cloud, and present that the Kondo cloud exhibits theresonant structure. I also evaluate the scattering cross section for the lightquark and the heavy quark, and discuss its effect to the finite size quarkmatter.
