  The one-dimensional Kondo lattice model is investigated by using bosonization
techniques and conformal field theory. In the half-filled band, the charge and
spin gaps open for the anti-ferromagnetic Kondo coupling. Away from
half-filling, the paramagnetic metallic state is characterized by the fixed
point of Tomonaga-Luttinger liquid with the {\it large} Fermi surface in
accordance with known results. It is suggested that as the electron density
approaches half-filling, both of spin and charge susceptibilities may show a
divergence property.
