  We report the existence of the charge density wave (CDW) in the ground state
of 1D Kondo lattice model at the filling of n=0.75 in the weak coupling region.
The CDW is driven by the effective Coulomb repulsion mediated by the localized
spins. Based on our numerical results using the density matrix renormalization
group method, we show that the CDW phase appears in the paramagnetic region
previously known as the Tomonaga-Luttinger liquid. The emergence of this phase
serves as an example of CDW phase induced without bare repulsive interactions,
and enriches the phase diagram of the 1D Kondo lattice model.
