Impedance simulation was performed for analysis of a branch structure porous carbon electrode composed of macropores and mesopores. Theoretical equations were derived by introducing a new branch structure transmission line model, in which the charge-transfer reactions in the pores are considered. The loci of the straight line with angles at 22.5° and semicircle were observed in the high and low frequency ranges. It was found that the charge-transfer resistance in the mesopore interface had no influence on the loci of the straight line.
