Resistance measurements for the one dimensional organic conductor (TMTSF) <SUB>2</SUB>AsF<SUB>6</SUB> have been perfonned to investigate the chiral surface state, which is realized on the side of the single crystal in the field induced spindensity-wave (SDW) phases (quantum Hall phases). The interlayer resistance in the integer quantum Hall phase is found to show a steep increase below the SDW transition, have a maximum and then become constant. The steep increase of the resistance results from the carrier decrease due to the nesting of the one dimensional Fermi surfaces. The temperature independent resistance at low temperatures suggests diffusive motion of the electron by the formation of the chiral surface state. The sharp peak of the interlayer resistance is found between the adjacent quantum Hall phases at low temperatures.
