Abstract
Arguments are presented that in the one-dimensional Kondo lattice model -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 and are estimated to be of the order of .
