Abstract

A conductive composition may include a conductive polymer (A) having an acidic group, and a basic compound (B), wherein: an X/Y area ratio is 0.046 or less, 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 ZS/ZR ratio is 20 or less. ZS is a maximum fluorescent intensity value in a range of 320 to 420 nm when a fluorescence spectrum is measured at 230 nm excitation wavelength in a solution obtained by diluting the conductive composition with water to adjust the conductive polymer (A) solids content to 0.6 wt. %. ZR is a maximum Raman scattering intensity value in a range of 380 to 420 nm when a fluorescence spectrum of water is measured at 350 nm excitation wavelength.
