An electrochemical anion doping-undoping process of cis-polyacetylene, (CH)//x, was investigated in 1 mol dm** minus **3 LiClO//4 or LiBF//4 in propylene carbonate by the FFT impedance measurement. This could be applied to the system with time-variation because of its high speed measuring duration. The doping-undoping process of the anion was represented by the Randles-type equivalent circuit, considering the corrective term concerned with surface roughness. The impedance behavior of the doping-undoping process was pursued by the variation of resistive component, Rr. The value of Rr was mainly reflected by the dopant concentration at the surface.
