We have measured the electrical resistivity and thermoelectric power (TEP) of single wall carbon nanotube (SWCN) network. The resistivity result can be fitted to the variable range hopping (VRH) type conduction formula. The room temperature TEP is about 30 approx. 60 μ V/K and the overall temperature dependence of the TEP is similar to that of the disordered alloy which shows the electron-phonon enhancement of TEP. By applying the magnetic field up to 6 Tesla, the magnitude of the TEP is reduced by approx. 2 μ V/K while the overall temperature dependence is more or less the same. The results are discussed by the heterogeneous model which was adapted to the conducting polymers.
