NbSe2 nanotubes were studied by scanning tunneling microscopy (STM). Topographic images of NbSe2 nanotubes on the substrate of HOPG were taken at room temperature. The length of nanotubes is estimated as 300-2000 nm. Diameter of nanotubes is found to be several nm, which is much smaller than that of multi-walled nanotubes, suggesting single-walled one. The bundle structure, which consists of several ten nanotubes, and Y-junction were found similarly to carbon nanotubes.
