We investigate properties of the spontaneous chiral symmetry breaking and the color superconductivity in finite density QCD by using non-perturbative renormalization group. When we lower the renormalization scale, effective 4-fermi interactions are generated by the gauge interactions, which consequently bring about the spontaneous symmetry breakdown at the low energy scale. We analyze the behavior of these 4-fermi coupling constants to obtain the critical density for color superconductivity at zero temperature.
