According to the method for producing bis(fluorosulfonyl)imide salt of the present invention, the method for producing fluorosulfate, and the method for producing bis(fluorosulfonyl)imide onium salt, first, an aqueous solution is prepared by dissolving a mixed liquid containing bis(fluorosulfonyl)imide and fluorosulfonic acid in water. Then, the aqueous solution is neutralized with an alkaline compound, producing bis(fluorosulfonyl)imide salt and fluorosulfate. In the methods, bis(fluorosulfonyl)imide salt, fluorosulfate, and bis(fluorosulfonyl)imide onium salt can be obtained safely and easily.
