The purpose of the present invention is to provide a novel organic solvent dispersoid for a conductive polymer/polyanion complex with which a film having exceptional conductivity and minimal decline thereof over time can be formed on a variety of substrates when the dispersoid is used as an additive to a variety of coating agents. The invention comprises using an organic solvent dispersoid containing a conductive polymer/polyanion complex that comprises a polythiophene and a sulfoanion-group-containing polymer and has a prescribed structure, an amine compound having a prescribed structure, an alcohol-soluble compound having a prescribed structure, and an alcohol-containing organic solvent.
