Abstract: This method for analysis processing by using measured impedance spectrum data includes: a step for determining whether to reset the maximum value and/or the minimum value of logarithmic relaxation time corresponding to a measured logarithmic frequency on the basis of the measured impedance spectrum data; a step for setting the number of equal-interval divisions within the range of the logarithmic relaxation time set in the determination step; and a step for analyzing parameters R∞, T, L, and Rl for the range of the set logarithmic relaxation time so as to satisfy a prescribed expression (A) by applying a regularized least-squares method.
