Abstract: There is provided a conductive composite having excellent conductivity and able to form a conductive film with which film loss in a resist layer is low. The conductive composite of the present invention includes a conductive polymer and a surfactant. When a critical micelle concentration of the surfactant is less than 0.1% by mass, a content of the surfactant is 5 parts by mass or more with respect to 100 parts by mass of the conductive polymer. In addition, when the critical micelle concentration of the surfactant is 0.1% by mass or more, the content of the surfactant is more than 100 parts by mass with respect to 100 parts by mass of the conductive polymer.

Abstract: A conductive composition comprising a conductive polymer (A) having an acidic group, and a basic compound (B), wherein: an area ratio (X/Y) is 0.046 or less as calculated by an specific method, which is a ratio an area (X) of a region corresponding to molecular weight (M) ranging from 300 to 3300, relative to an area (Y) of an entire region ascribed to the conductive polymer (A); or a ratio, ZS/ZR, is 20 or less, wherein the ZS is a maximum value of fluorescence intensity in a wavelength region of 320 to 420 nm when a fluorescence spectrum is measured using a spectrofluorometer at an excitation wavelength of 230 nm with respect to a measurement solution obtained by diluting the conductive composition with water so as to adjust solids content of the conductive polymer (A) to 0.6% by mass, and the ZR is a maximum value of Raman scattering intensity in a wavelength region of 380 to 420 nm when a fluorescence spectrum of water is measured using a spectrofluorometer at an excitation wavelength of 350 nm.
