The objective of the present invention is to provide a clear conductive material with less turbidity, methods for producing and purifying the conductive material, and a nonaqueous electrolyte solution and an antistatic agent which contain the conductive material. The conductive material of the present invention comprises a fluorosulfonylimide salt represented by the following formula (1): wherein X is F of 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, wherein a concentration of the fluorosulfonylimide salt is 0.1 mol/L or more, and a turbidity is 50 NTU/mol-LiFSI or less; and the production method of the present invention comprises the step of filtering a solution comprising the fluorosulfonylimide salt and the organic solvent by using a filter medium comprising the specific material.
