Carbon nanotubes on metal(SUS304) substrates were synthesized by using micro-wave plasma-enhanced chemical vapor deposition at $650^{circ}C$ with gas mixture CH$_4$(11%) and H$_2$(89%). Their structure was investigated by scanning electron microscopy and transmission electron microscopy. Raman spectroscopy was also used to justify the structure and crystallinity of graphite sheets. High-resolution transmission electron microscopy images clearly showed carbon nanotubes to be multwalled. The measured turn-on field and current density obtained from I-V measurement were 4.4 V/$mu extrm{m}$ and $8.4 imes10^1mu extrm{A}/ extrm{cm}^2$, respectively.
