Abstract
A conductive material includes metal nanowires and an extensible copolymer having an N—C═O structure and combined with the metal nanowires. The conductive material has excellent elongation properties and has an electrical resistance that is unlikely to increase even when the conductive material is extended. A method for producing a conductive material includes: a copolymer production step of polymerizing a plurality of monomers including a growth direction control monomer that has an N—C═O structure and controls a growth direction of metal nanowires to produce an extensible copolymer; a reaction step of reacting a metal compound in a solvent containing the copolymer to grow metal nanowires in a longitudinal direction; and an extraction step of extracting a product from the solution after the reaction.
