  Arguments are presented that in the one-dimensional Kondo lattice model
f-electron spins participate in filling of the Fermi sea. It is shown that in
its paramagnetic phase this model belongs to the spin-1/2 Tomonaga-Luttinger
liquid universality class. The ratio of the spin and charge velocities v_s/v_c
and K_c are estimated to be of the order of (T_K/E_F)^{1/2}.
