The present invention provides a method for easily removing metal impurities from an indole derivative trimer containing the metal impurities, which method involves mixing the indole derivative trimer containing the metal impurities with an imidazole compound in a solvent comprising water under heating, and filtering and separating the indole derivative trimer, from which the metal impurities have been removed, from the obtained mixture. Further, mixing a protonic acid allows the doping of the indole derivative trimer to be conducted simultaneously with the metal impurity removal, whereby the indole derivative trimer can be used as an electrode active substance of an electrochemical cell.
