• Magnetic impurity effects on metallic carbon nanotubes are studied theoretically. The resolvent method for the multichannel Kondo effect is applied to the band structure of the k-p perturbation hamiltonian. The local non-Fermi liquid behavior is realized at temperatures lower than the Kondo temperature T_K. The density of states of the localized electron has a singularity ~ |ω|^<1/2> which gives rise to a pseudo gap at the Kondo resonance in low temperatures. The temperature dependence of the electronic resistivity is predicted as T^'<1/2>, and the imaginary part of dynamical susceptibilities has the |ω|^<1/2> dependence. Possible experimental observations are discussed.
