A metal salt produced as a by-product is simply and efficiently removed, and fluorosulfonylimide salts such as N- (fluorosulfonyl) -N- (fluoroalkylsulfonyl) imide salt and di (fluorosulfonyl) imide salt are obtained. Methods of manufacture and fluorosulfonylimide salts are provided. A process for producing a fluorosulfonylimide salt, which comprises reacting a compound represented by general formula (II) with an onium salt to obtain a compound represented by general formula (VI); A step of reacting the compound represented by the general formula (VI) with an alkali metal compound to obtain a compound represented by the general formula (III). In the above Scheme, R 1 is 11 to Group 15, period 4 to 6 of the elements (except, arsenic and antimony are excluded) is at least one element selected from the group consisting of, R 2 Is an alkali metal, R 4 is fluorine or a fluorinated alkyl group having 1 to 6 carbon atoms, R 5 is an onium cation, m is an integer of 2 to 3, and n is a valence of the onium cation R 5 , Where l is 1.
