We have performed angle-resolved photoemission spectroscopy on Nb3Te4, which has zigzag Nb-Nb chains along the c-axis in the crystal. We found a dispersive Nb 4d band near the Fermi level (EF) which crosses EF midway between the center and the boundary of the Brillouin zone in the chain direction. The intensity of the Nb 4d band was found to be substantially suppressed near/at EF, showing a typical Tomonaga-Luttinger liquid behavior of 1D metals. On the other hand, a clear Fermi-edge cutoff, characteristic of 2D or 3D metals, is seen for this Nb 4d band. All these results suggest that Nb3Te4 is a quasi 1D metal with admixture of 2D or 3D character due to the finite inter-chain interaction.
