• We study the internal structure of a non-Abelian vortex in color superconductivity with respect to quark degrees of freedom. Stable non-Abelian vortices appear in the Color-Flavor-Locked phase whose symmetry SU(3)_<C+L+R> is further broken to SU(2_<C+L+R>⊗U(1)_<C+L+R> in the vortex cores. Fermionic description of vortices is made possible by the Bogoliubov-de Gennes (B-dG) equation. Quark spectra in the vortex are obtained from the B-dG equation by treating the diquark gap having the vortex configuration as a background field. We find that there are massless modes (zero modes) well-localized around a vortex, in the triplet and singlet states of the unbroken symmetry SU(2)_<C+L+R>
