Process for producing sulfonylimide compound (represented by the formula (I) MN(SO2R f1) (SO2R f2)) industrially easily at a low cost in an efficient manner, wherein the process comprising reacting a sulfonyl fluoride represented by the formula (II) R f SO2F with ammonia anhydride or an ammonium salt in the presence of a fluorine compound represented by the formula (III) MF. The above M represents any one of Li, Na, K and Cs among alkali metals of group Ia in the periodic table. The above R f 1 and R f2, which may be the same of different, respectively represent any one of a straight chain or branched compound of a fluoroalkyl, perfluoroalkyl, fluoroallyl or fluoroalkenyl group having 1 to 12 carbon atoms, and R f in the above formula (II) represents the same group as R f1 or R f2 in the formula (I).
