The characterization of electrical property of multi-walled carbon nanotubes （MWCNTs） on a nanometer scale is essential for their potential application in nano-electronic devices. The MWCNTs were synthesized on Fe2O3/SiO2/Si substrate and Pt plate substrate by simple thermal chemical vapor deposition （STCVD） technique and the electrical measurements of individual MWCNT grown on silicon substrate and Pt plate substrate were performed by home-made ＇nano-manipulator＇, respectively. According to current-voltage curves obtained in the experiments the current density that the MWCNTs can carry is calculated to be about 10^7 A/cm^2, which is much larger than that of normal metals.
