We report ^<125>Te and ^<139>La NMR studies for single crystals of LaTe_3 between 10 and 160K under an applied field of H = 7.4841T. We observed the broad ^<125>Te(1) NMR signals of metallic Te(1) sheets with a superlattice modulation and the sharp ^<125>Te(2) and ^<139>La NMR signals of LaTe(2) bi-layers. Temperature dependence of ^<125>Te(1) nuclear spin-lattice relaxation times of the modulated Te(1) sheets obeys a modified Korringa relation. The results indicate that the electronic state on the Te(1) sheets is a Landau-Fermi liquid on a misfit superlattice or a Tomonaga-Luttinger liquid in a two-dimensional charge-density wave ordering state.
