Angle-resolved photoemission spectroscopy of ZrTe3 has been performed from room temperature(T) down to 6 K (across Tcdw = 63K) to study the charge-density-wave (CDW) fluctuation effects in a metallic CDW compound having Fermi surface (FS) sheets with differing dimensionality. While spectra on the 3-dimensional(D) FS show typical Fermi-Dirac function-like T-dependence, those along the quasi 1-D FS show formation of a pseudogap, starting at a much higher T than Tcdw. Simultaneously, a van-Hove singularity consisting of the quasi 1D FS intersecting the 3D FS shows increase of coherence. This demonstrates the role of CDW fluctuations on the spectral function, and relation to the dimensionality of the states, in a metallic CDW system.
