Conductive material and manufacturing method and purification method for same, and non aqueous electrolyte solution and antistatic agent using said conductive material

A method for producing a conductive material,

• wherein the conductive material comprises a fluorosulfonylimide salt represented by the following formula (1):
• wherein X is F or a C1-6 fluoroalkyl group,
• and at least one organic solvent selected from the group consisting of a carbonate solvent, an ester solvent, a ketone solvent and an alcohol solvent, and
• wherein the conductive material has an ion conductivity,
• comprising the step of filtering a solution comprising the fluorosulfonylimide salt by using a filter medium comprising at least one material selected from the group consisting of a cellulose resin, a polyester resin, a silicon dioxide material and activated carbon.
