The invention provides an electrically conductive polyaniline composition comprising polyaniline which contains at least one of novolac resins selected from the group consisting of phenolsulfonic acid novolac resin and naphtholsulfonic acid novolac resin as a dopant. The electrically conductive polyaniline composition is obtained by contacting polyaniline with an aqueous solution of the novolac resin to dope the polyaniline with the novolac resin.The invention further provides an electrically conductive polyaniline film which comprises the polyaniline containing the novolac resin as a dopant. The electrically conductive polyaniline film is obtained by contacting film of polyaniline with an aqueous solution of the novolac resin to dope the polyaniline.
