Popis:	In the charge ordering (CO) state of the quasi-one dimensional conductors (TMTTF) 2 SbF 6 , we measured the current-voltage relations by the pulse current method at ambient pressure. From the measurement, we found that the conductivity is constant at low electric field regime and increases with field above a certain field. It is similar to the nonlinear conduction due to the ordinary density wave (DW) sliding. However, the magnitude of the threshold electric field was larger than that in the DW system. We will discuss the origin of the non-linear electric conduction in the CO state of (TMTTF) 2 SbF 6 and the apparent similarity with it by the DW sliding.
