Abstract: Provided is a conductor material having high conductivity. The conductor material according to an embodiment of the present disclosure has a configuration in which a conjugated polymeric compound having an electron donating group containing a heteroatom in a side chain is doped with a dopant containing an anion selected from a nitrogen anion, a boron anion, a phosphorus anion and an antimony anion, and a counter cation. The anion is preferably an anion represented by Formula (1) below: where R1 and R2 are identical or different, and each represent an electron withdrawing group; and R1 and R2 may be bonded to each other to form a ring with an adjacent nitrogen atom.
