The present invention provides an electroconductive composition containing an aqueous solvent-soluble electroconductive polymer as represented by formula (1) which has a pi-electron conjugated systemand exhibits electroconductivity in electron conducting mechanism and an aqueous solvent-soluble resin. By using the electroconductive composition of the invention, reduction in resistivity and enhancement in electroconductivity of the coating film can be achieved, and the coating film can be suitable used, for example, as an electroconductive coating film, as coating film for a coated article andin an anode buffer layer of an organic electronic device.
