Provided is a conductive composite having excellent conductivity and being capable of forming a conductive film that leads to less film loss of a resist layer. This conductive composite contains a conductive polymer and a surfactant. When the critical micelle concentration of the surfactant is less than 0.1 mass%, the content of the surfactant is at least 5 parts by mass to 100 parts by mass of the conductive polymer. When the critical micelle concentration of the surfactant is at least 0.1 mass%, the content of the surfactant is more than 100 parts by mass to 100 parts by mass of the conductive polymer.
