Conductor, conductive composition and laminate

A conductor, comprising:

• a substrate;
• and
• a conductive coating film laminated on the substrate,
• wherein the conductive coating film has a surface resistance value of 5×1010Ω/□ or less,
• the conductive coating film has a surface roughness (Ra1 ) measured by a stylus profiler of 0.7 nm or less, and
• a surface roughness (Ra2 ) measured by a scanning probe microscope of 0.35 nm or less, and
• the conductive coating film is formed by a process comprising drying a conductive composition comprising a conductive polymer (A) and a surfactant (B), wherein the surfactant (B) comprises a water-soluble polymer (C) having a nitrogen-comprising functional group and a terminal hydrophobic group and having a molecular weight ranging from 500 to 1500, and the surfactant (B) comprises a compound (D1) with an octanol-water partition coefficient (Log Pow) of 4 or more such that an amount of the compound (D1) in the conductive composition is 0.001 mass % or less, relative to the total mass of the conductive composition.
