PROBLEM TO BE SOLVED: To provide a method for producing a fluorosulfonylimide ammonium salt with good efficiency in which the incorporation of metal impurities which deteriorate electrolyte properties and the like is suppressed as much as possible and to provide a method for producing a fluorosulfonylimide salt without containing metal impurities from a fluorosulfonylimide ammonium salt.SOLUTION: There is provided a method for producing a fluorosulfonylimide ammonium salt represented by the formula [II] (wherein, Rrepresents a fluoroalkyl group having 1 to 6 carbon atoms or a fluorine atom), which comprises reacting a compound represented by the formula [I] (wherein, Rrepresents a fluoroalkyl group having 1 to 6 carbon atoms, a fluorine atom or a chlorine atom) and a fluorinating agent represented by the formula [III] (wherein, p represents a real number of 1 to 10). |
